This PR implements the Normalize operators in Weight Paint mode for
GPv3:
- Normalize weights of the active vertex group. This operator normalizes
all the vertex weights in the active vertex group to a value between 0.0
and 1.0.
- Normalize All. This operator normalizes the weights of all vertex
groups, so that for each vertex, the sum of the weights is 1.0. Weights
of locked vertex groups are not changed. By default, the active vertex
group also stays unchanged, unless it's necessary to reach a normalized
state.
The operators are added to the 'Weight' menu in Weight Paint mode.

This rename the `Cutter` tool's name, code and icon to `Trim`.
The legacy Grease Pencil code is unchanged.
This was discussed in the 2024-07-30 Grease Pencil Module Meeting.
Reasons for the change:
- Match the `Trim Stroke Ends` setting on brushes.
- Match the `stroke_trim` operator.
- Name is more clear and more commonly used.
- Frees the name for a future boolean cutting tool.

When an NLA strip is in tweak mode, the Action editor no longer allows
switching the assigned slot. This is now consistent with it also not
allowing switching of the Action.
The slot used by the NLA strip can be changed in the NLA strip
properties panel of the NLA editor, in the same way that the Action
itself can be changed there.
This adds the following operators:
* Set Vertex Color
* Reset Vertex Colors
* Invert
* Brightness/Contrast
* HSV
* Levels
Also populates the `Paint` menu with them in vertex paint mode.

Enums that are displayed as icon-only should have their icons defined
in RNA, not just through the layout in Python. That way they are shown
in the dropdown itself and users make the connection between the listed
item label and the icon while collapsed.
As per the human interface guidelines, do not use the same icon in
consecutive items within a group in a menu.
* Operator Search in Top Bar's Edit menu
* Viewport Render Keyframes in Viewport's View menu
The Parent Node Tree operator button to go up a level in nested
node trees is always visible in the header, regardless if we are
currently in a nested tree or not.
Only show the button when it is actually possible to go a level up.
This frees up space in the header when at the top level.
This option is meant to ignore any material locking when it
comes to editing strokes that might use locked materials.
There were some issues with the current implementation.
* The name did not reflect what it was supposed to do, so it
was renamed to `ignore_locked_materials`.
* The description of the option has been updated to better
reflect the behavior.
* Some util functions have been refactored

For an NLA strip to use a slotted Action, it needs to specify which slot
to use in that action. This is now handled by two new properties on the
strip in DNA & RNA: `action_slot_handle` and `action_slot_name`.
These serve the same purpose as their counterparts on the `AnimData`
struct.
Note that this commit does NOT add NLA evaluation support for slotted
Actions. It merely allows assigning them. Evaluation, tweak mode
support, etc. will be implemented in future commits.

The cfl_condition default was changed in 9a0a75eff0 with the intention
of making liquids behave better. However, that degraded the simulations of fire.
Now the property will be set to its old value if the quick smoke operator is used.
Can't think of a great way always use the old value for smoke simulations for now.
This PR implements the "Smooth" operator in Weight Paint mode for GPv3.
The Smooth operator smooths the weights in the active vertex group by
applying a gaussian blur to the vertex weights.
The operator has two properties:
- `factor` (0.0 - 1.0): The extent to which the smoothed weight is
applied to the original weight, where 0.0 is 'keep the original weight'
and 1.0 is 'replace fully with the smoothed weight'.
- `repeat`: The number of times the smoothing is executed. A higher
value means more smoothing.
The operator is added to the 'Weight' menu in Weight Paint mode.

This PR allows users to select a GPU backend.
In the system tab of the user preferences the GPU backend can be selected in the `Display Graphics` panel.
It will require a restart of Blender before the changes become effective.
During startup minimum requirements are checked. Blender will switch automatically
to OpenGL when no compatible Vulkan device could be detected. A dialog will be shown
to inform the user.
The setting of the in the `Display Graphics` panel are still overridden when blender is started
using the `--gpu-backend` option. When starting blender with `--debug-gpu` the backend
detection will print to the console.
See PR for detailed information and screenshots of the UI.

- Move sys_info into an internal module to avoid having so many
top level modules for Blender's internal functionality.
- Rename system_info sub-modules that pre-fill URL's for clarity.
- Move top-level exception handling into the operator.
- Report an error if an unexpected exception occurs.
- Use `Exception` instead of `BaseException` as there is no reason to
catch the additional exceptions.
- Remove use of sys_info from the command line example,
replace with in-lined system info.
Add Action + Action Slot selectors to various Property Editor tabs.
This follows the pattern established in
f917b60036.
Support for `CacheFile` data-blocks is not included here. That needs
some discussion, as currently its interface is part of the Modifier
stack (and thus implemented in C++ and not Python, and using a
different layout).
Since this PR is about adding to the Property Editor, some data-blocks
that have no representation there are thus excluded (like `Mask`).
Even when they could actually use an Action+Slot selector somewhere.

The new Action selector (51fd355c01) avoids the need to use
`space_data.action` in the dope sheet (that attribute was a bit of a
hack; the new Action selector was made to avoid that). It failed to take
the dope sheet's shape key mode into account properly, though. This is
now fixed.

GPv3 is no longer really a experimental feature now and the
experimental option is also removed already, so it does not
make much sense keeping this branch in the UI.
Add two new operators, `anim.slot_new_for_id` and
`anim.slot_unassign_from_id`. These are used in the Action editor and
the Animation panels in the Properties editor, to respectively create a
new Action Slot for an ID and to unassign whatever slot is currently
assigned to that ID.
The latter operator also replaces the C++ operator
`anim.slot_unassign_object`, which was specifically made for the
Dopesheet header. The Python ones are generic enough to be used there
too.

In the Properties editor, add Action selectors to the Material
properties and the Camera properties.
For the Material, two Action selectors are shown: for the Material
itself and for its shader node tree. Those are separate IDs of different
types, and thus will always have separate Actions (until the Slotted
Actions are commonplace).
When the 'Slotted Actions' experimental feature is enabled, also show
the Action Slot selector underneath each Action selector.
The Animation panel in the Properties editor is (by default) always at
the bottom, just above the Custom Properties panel.

This node hashes various types into an integer. Note that hashes
cannot generally used as unique identifiers because they are not
guaranteed to be unique. It can be used to generate somewhat
stable randomness though in cases where White Noise does not
offer enough flexibility.
It uses hash functions from BLI_noise.hh. These are also used in
the White Noise node.

Previously, all errors, warnings and info messages were propagated from the node
that generates it to the top level node group. This is a good default, but may
not always be desirable. For example, someone may build a node group asset that
generates some warning that is irrelevant to the user to the asset. Now, the
asset author can selectively disable propagating warnings from that node.
Each node has a new `Warning Propagation` setting. It controls if warnings from
this node should be propagated to the parent group node. By default, everything
is propagated. One can also choose to propagate nothing, only errors or only
errors and warnings.
Note, this does not affect whether the warning is shown in the node itself, only
if the warning is propagated one level up!
Pull Request: https://projects.blender.org/blender/blender/pulls/126786
This implements the `Warning` node that allows node groups to communicate
expectations about input values to the user.
By default, the `Warning` node is only evaluated if the node group that contains
it is evaluated in any way. This is better than always evaluating it, because
that could trigger lots of unnecessary evaluation in parts of the potentially
large node tree which should be ignored. In this basic mode, the output of the
node should not be connected to anything and it must not be in a zone.
For more fine-grained control for when the `Warning` node should be evaluated,
one can use the boolean output which is just a pass-through of the `Show` input.
If this output is used, the `Warning` node will only be evaluated if its output
is used. A simple way to use it is to control a Switch node with it that e.g.
"disables" a specific output when the inputs are invalid. In this case, the
`Warning` node may also be in a zone.
The node allows the user to choose between 3 severity levels: Error, Warning and
Info. Those are the same levels that we use internally. Currently, the error and
warning mode are pretty much the same, but that may change in the future.

Add new operator `anim.slot_new_for_object`, which creates a new action
slot for the active object. Since this slot is created on the action
used by the object, it requires that this action exists and is a
layered/slotted action (which by definition includes empty actions).

Add Metallic BSDF Node to the shader editor.
This node can primarily be used to create more realistic looking
metallic materials than the existing Glossy BSDF node.
This commit does not add any new closures to Cycles, it simply exposes
existing closures that were previous hard to access on their own.
- Exposes the F82 fresnel type that is currently used by the
metallic component of the Principled BSDF. Results should match
between the Metallic BSDF and Principled BSDF when using the same
settings.
- Exposes the Physical Conductor fresnel type that was previously
limited to custom OSL scripts. The Conductor fresnel type accepts
IOR and Extinction coefficients to define the appearance of the
material based off real life measurements.
EEVEE only supports the F82 fresnel type with internal code to convert
the the physical conductor inputs in to a colour format for F82,
which can lead to noticeable rendering differences with
some configurations.

Adds the ability to connect and disconnect strips in the VSE.
- Connected strips have an icon indicating their status, and attempting
to select one connected strip selects all other connected strips in
that chain.
- If the user attempts to connect a strip that is already connected to
other strips, that strip will disconnect itself from others before
connecting to new strips.
- Preview selection also works in bulk if multiple video strips are
connected together in the timeline.
- When adding new strips from the Add menu or the File Browser, strips
from the same file are connected by default. There's an option to
turn this off in Editing > Video Sequencer user preferences.
- It is possible to individually tweak strips/handles and ignore
connections with Alt+Click.
- This shortcut overrides the old keymap item for "Linked Handle"
selection. The property still exists if people want to use that
shortcut for its old purpose.
- To make sure that connections remain valid even after duplication,
I've added a condition to `seq_new_fix_links_recursive` that also
updates connections using the `seq->tmp` var. (A note -- I've updated
the comment for this field in `DNA_sequence_types.h` because the var
is only used for duplication now. It was once present in
`select_more_less_seq__internal` to be used for linked selection but
is gone now).
- There are also functions to cut one-way links and make sure that
all strips are bidirectionally connected after duplicating.

Support segment mode in Grease Pencil v3 selection operators.
This is a continuation of #109221.
Segment selection works in multiple stages:
1. When enabled, the 2D evaluated lines for all visible curves are
entered into a BVH tree. This tree is used to find intersections later
on. All the visible drawings are in the tree, an `OffsetIndices` array
is used to record ranges of BVH elements for each drawing.
2. Primary selection functions get alternative versions that produce an
`IndexMask` instead of writing directly to selection attributes. This
makes it possible to detect select actions on points that are already
selected. Using a delta of selection attributes for this is not enough
to detect such user actions (and inefficient).
3. In segment mode the `IndexMask` is extended to fully cover segment
points (or exclude them when deselecting respectively). This first
performs and intersection test using the BVH tree, then finds all point
range with selected elements.
4. Finally the extended index mask is applied to selection attributes as
usual.
