Numerical inputs have little arrows on the left and right to allow
quick increment/decrement of the value. But these are only shown on
hover, which does not help if using a device that does not have a hover
state (some pens, most touch). This PR adds a user preference to show
them always.

Add "Reduce Motion" option to a new `Accessibility` panel under
Preferences, User Interface.
"Reduce Motion" avoids non-essential animation effects, especially
useful for those experiencing motion sickness/vertigo.
It affects:
* Region open/close.
* Pie menus animation.
* Smooth views.
This panel in the future could host common accessibility settings such
as "Increase Contrast" or font size and weight controls that currently
are part of themes.
See PR for details and screenshots.

This PR updates the VSE strip modifiers interface.
It now uses the same design as the object modifiers.
Changes:
* Except for the "Mask Input" subpanel, the modifier UIs are unchanged.
* Modifiers can now be rearranged using drag & drop.
* Additionally, there is now an active strip modifier. This is exposed
though python via `strip.modifiers.active`.
This is in part for !139634 which needs the concept of an active modifier.
Notes:
* The `modifier.cc` file included all the implementation of all modifiers.
With the addition of a another new callback in this PR, this file was
getting quite big so I split everything out into individual files for all
modifiers. The modifiers are getting registered at launch.
* The modifier panels are getting added using a UI template
(`template_strip_modifiers`) very similar to the object modifiers.

Use viewport navigation options in the orthographic view as well.
While the intention was to have the 3D-navigation preference only
impacting 3D views, inconsistencies between 2D/3D views tend to be
confusing for users, so use the same behavior in both.
Also expose the preference in the "3D Mouse" popup for 2D views as
this preference is used there as well.

Moving curve handle colors & size from space editors into common theme properties.
They are now shared by 3D Viewport, Image Editor, Graph Editor, and Movie Clip Editor,
instead of each of them having their own properties.
(Video in PR)
---
Details:
- NURB U/V lines, active spline, and last selected point colors were defined
in `rna_def_userdef_theme_spaces_curves` but were optional and only called by
3D viewport. Since no other editor calls that function anymore, I removed it and
moved those properties directly inside `rna_def_userdef_theme_space_view3d`.
- In Image Editor & Movie Clip Editor (Mask mode), curves don't ever show
selection colors, and Vector handles are generally never visible, that is
bug/missing in Blender in general, not a result of this PR.
- Handle vertex size were included in Dope Sheet and NLA, where handles don't
exist. Now as a side effect they're removed as well.

The W channel in quaternion and axis-angle F-Curves is now themeable
(defaulting to yellow), instead of incorrectly blending the X and Y axis
theme colors.
The original blending math did not take into account that the hue
channel actually wraps around, and so the blended color became blue
instead of the intended yellow.
Instead of fixing the math, the theme has been expanded for this W axis.
The default color is set to the mathematically correct yellow.

Prefer "active" so the settings can still be changed,
typically this is preferred unless changing them would cause problems.
Also assign "active" immediately after assignment,
following the convention use elsewhere in scripts.
This includes a new list structure type and socket shape, a node
to create lists, a node to retrieve values from lists, and a node to
retrieve the length of lists. It also implements multi-function support
so that function nodes work on lists.
There are three nodes included in this PR.
- **List** Creates a list of elements with a given size. The values
are computed with a field that can use the index as an input.
- **Get List Item** A field node that retrieves an element from a
a list at a given index. The index input is dynamic, so if the input
is a list, the output will be a list too.
- **List Length** Just gives the length of a list.
When a function node is used with multiple list inputs, the shorter
lists are repeated to extend it to the length of the longest.
The list nodes and structure type are hidden behind an experimental
feature until we can be sure they're useful for an actual use case.

This change enables HDR support for wayland as an experimental feature.
It supports both non-linear extended sRGB and un-clamped sRGB.
Windows isn't supported as the HDR settings are not accessible via an
API and would require similar settings that games use to configure the
monitor. Adding those sliders isn't what we would like to add.
Vulkan (working group) is working on new extensions that might change
the shortcomings. It isn't clear yet what the extension will do and what
the impact is for applications that want to use it. When the extension
is out we should review at the situation again.

Remove the use_attribute_storage_write experimental option and always
write in the new format, which is supported by 4.5. The new format is
only used at runtime by point clouds currently but there is no reason
for it to be an option at this point.
This is a second commit repeating 84212bae4b
after that was reverted. Issues that came up with Grease Pencil writing
have been resolved in the meantime.
The grid layout type for UI list is planned for removal in 5.0, see
blender/blender#110461.
In previous UI meetings, we talked about deprecating the Grid mode of
the UI list, which is not actually accessible in UI and was never used.
Nowadays, there is a new grid view that can be exposed in the API in
the future.
Initially, I wanted to remove references to layout_type in UI templates
in the text editor, because a lot of add-on developers on the
extensions platform base their lists on that code, and a lot of them
are therefore including soon to be deprecated code in their add-ons,
which I want to avoid in the future. But I thought we might as well
remove it from our python scripts as well, since it's just basically
redundant code that doesn't do anything. And also because many add-on
developers use bundled python scripts for references as well.

This enables the new .blend file format as described in #129309 and implemented
in 6a90382390 by default. This allows storing
blocks larger then 2GB inside the file. This is a necessary requirement to be
able to store e.g. meshes with more than a few hundred million vertices.
There is a new debug option that can be used to force Blender to write the older
file format. This is especially useful when using tools that have not been
updated to be able to read the new format yet.
Compatibility:
* Blender 4.5 is able to read the new format for a few months already, so 4.5
LTS will be able to read these files
(6a90382390).
* The internal `blendfile.py` which is used by `blend2json.py` has been updated
(d83bfee347).
* blender-asset-tracer (BAT) has been updated
(blender/blender-asset-tracer@f1ee7980b2).
* `blend_render_info.py` will be updated soon (#140341).

This allows to reduce the waiting time caused by
shader compilation on some GPU-driver combo.
A new settings in the User Preferences make it
possible to override the default amount of worker
threads and optionally use subprocesses.
We still use only one worker thread in cases where
there is no benefit with adding more workers
(like AMD pro driver and Intel windows).
It doesn't scale as much as subprocesses for material
shader compilation but that is for other reasons
explained in #139818.
Add some heuristic to avoid too much memory usage
and / or too many stalls.
Also add some heuristic to the default number of subprocess for
the platform that shows scalling.
Historically, multithreaded compilation was prevented by the
need of context per thread inside `DRWShader` module.
Also there was no good scaling at that time. But
nowadays numbers shows different results with
good scaling with reasonable amount of threads on many
platforms.
Even if we are going for vulkan in the next release
most of the legacy hardware will still use OpenGL for
a few other releases. So it is relevant to make this
easy improvement.

- Navigation modes has been redefined a bit and introduced in a form of
an enum so that new ones can me implemented in the future.
Additionally switching between modes shouldn't require any additional
configurations like inverting all the axes.
Currently there are only 2 modes implemented,
but 2 more are planned and will be proposed in follow-up PRs.
Implemented modes are:
- Object: works like "Orbit" option.
but has all axes implicitly inverted
- Fly: works the same as "Free".
- "Turntable" option has been turned into "Lock Horizon".
This single option works for both normal navigation and Fly/Walk
modes now.
- Pan and Rotation axes inversion has been removed from default
configuration.
- UI has been simplified following the design from #136880.
- Zoom Invert has been removed since it looks like a duplication of
`NDOF_PANZ_INVERT`.

Added WoA support status. Up to now there hasn't been a working stack
that allows Windows+ARM GPU+Blender work well together. There are render
glitches and occasional crashes. Currently we are investigating the
issues together with Qualcomm in order to improve the situation. However
for Blender 4.5 release Vulkan support should not be expected to work.
There have een some issues detected with core vulkan that are not
visible on other platforms.
Currently VR can have suboptimal performance when using the Vulkan
backend (#138977). Jereon has run various experiments and was unable
to resolve the issue. So in the meantime work on Vulkan VR performance
has been delayed until Blender 5.0.
Since Blender 4.5 is likely to release without a fix for the VR
performance issue. This commit adds an explicit note about it to the
user preferences.

Implementation of #127106.
This is just a visual representation of the field/single/grid
status of sockets to make the workflow more intuitive. With
a visual representation for volume grid sockets, volume features
should be unblocked for further development. The structure type
will also be used to distinguish list sockets in the interface.
Group input nodes now have a "Structure Type" option instead of
the existing "Single Value Only". Usually the auto option should be
enough, but in some cases where the inferencing cannot (yet) make
a clear determination, it can be helpful to choose a specific type.
The new visualization and the group input structure type option
are hidden behind a new experimental option for now.

At this point, with pen tilt functionality having received the following
changes recently:
* Consistency between platforms for what pen tilt values represent
* Inactive cursor visualization
* Invertable per-brush strength
The majority of the work that remains is wider testing and addressing
per-device issues, thus it makes sense to make this option available in
release builds.
By default, no brushes packaged with Blender have a non-zero Tilt
Strength, making this option opt-in by default.
The following brushes support this option:
* Draw
* Draw Sharp
* Flatten
* Fill
* Scrape
* Plane
* Clay Strips
With a non-zero Tilt Strength value on the brush, the normal of the
brush plane is tilted in the same direction as the user's pen, where a
perpendicular orientation for the pen matches the behavior with a Tilt
Strength of 0.

Rework internals of how VSE caching is done. Primarily to make all the
caching logic more understandable from development point of view, but
also has several user visible implications (more details in the PR):
- Simpler and fewer caching UI options,
- Disk cache is gone (primary reason: proxies are kinda the same thing),
- VSE cache size set in preferences is actual size used for VSE caches
now (previously caching stopped as soon as whole Blender used that
much memory, even if some memory usage was not about VSE at all),
- Certain scenarios of cache invalidation are faster now.

As described in #122398, implement read and write support for a new
attribute storage system. Currently this is only implemented to support
forward compatibility; the format used at runtime isn't changed at all.
That can be done one step at a time during the 4.5 and 5.0 development
cycles. A new experimental option for testing tells Blender to always
save with the new format.
The main benefit of the new structure is that it matches the attribute
system design, it allows for future attribute storage optimization, and
each attribute is an allocated struct, which will give pointer stability
for the Python API.
The next step is to connect the attribute API and the RNA API to
AttributeStorage for the simplest geometry type, point clouds.

This is implements option 1 of #129309. It contains a few changes:
* Split `BHead8` into `SmallBHead8` and `LargeBHead8`. The latter is the new one
and uses `int64_t` for array sizes instead of just `int`. That applies to to
buffer size in bytes (`len`) and the array size (`nr`).
* The first .blend file header (the first few bytes of the file) are updated
according to #129309.
* Support reading files with that use `BHead4`, `SmallBHead8` and `LargeBHead8`.
* New option in the preferences that controls whether new files are written with
the older `SmallBHead8` or the new `LargeBHead8`. The new file format is
disabled by default. Potential unofficial 32 bit builds (#67184) always write
`BHead4`, but can read all types (in theory anyway, can't test it).
Note that there are other places in Blender that don't fully support arrays this
large. E.g. I noticed that the spreadsheet currently can't scroll all the way
down.
The experimental option can be removed once we are in the 5.0 branch, at which
point only 4.5 will be able to open the files saved with 5.0.

Previously the device selection was only shown when Blender was started
with the Vulkan backend. However most users don't know that this feature
exists. By also showing the device selection when the backend is changed
in the preferences, will motivate users to revisit the system tab and
see what can be selected.
Another option is to have the device selection fully working even when
running using OpenGL. Technically possible but it requires to mingle Vulkan
with OpenGL data in gpu globals.

In the past couple months, the basic operations needed for a new object
type were implemented, as well as basic edit mode tools. With that, the
object type is in a good enough state that it doesn't need to be hidden
behind an experimental option. That also resolves some inconsistency,
because the object type is already created by geometry nodes and used by
importers; it's weird that you can't add it manually as original data.
This also removes the "bounds" drawing flag for the object created from
the add menu. It's unnecessary now and there was even a TODO comment.
