Geometry nodes can't be evaluated when the node tree is not available. This
never worked before and the modifier evaluation was "cancelled" later on before
already. However, new code in the modifier evaluation requires the modifier to
be cancelled earlier already which is what this patch does.

This removes the include `UI_interface_layout.hh` from
`UI_interface_c.hh`, and in many places this swaps the include
from `UI_interface.hh` to `UI_interface_layout.hh`.
Also, cleanups some `UI_interface.hh` includes with
`UI_interface_icons.hh` or `UI_interface_types.hh`
This replaces uiLayout aligment API with uiLayout methods,
following uiLayout refactors and the Python API naming.
Also this converts the layout aligment enum to a fixed enum class.

Remove the last uses of `BKE_boundbox_init_from_minmax` in
favor of the newer `bounds::corners`. Besides clearer naming
and better ergonomics, it's also inline-able which seems to be a
good thing for such a simple function.
In order to get the same behavior as before I changed the
C++ bounds function to give the same vertex order as the
older function.

This commit implements #125759.
It removes:
* Blender does not build on big endian systems anymore.
* Support for opening blendfiles written from a big endian system is
removed.
It keeps:
* Support to generate thumbnails from big endian blendfiles.
* BE support in `extern` or `intern` libraries, including Cycles.
* Support to open big endian versions of third party file formats:
- PLY files.
- Some image files (cineon, ...).

Similar to the recent fix 457cccd964.
There was another code path which could pass in the wrong time into USD
for certain Mesh Sequence Cache scenarios.
I was not able to craft a faulty scenario by hand to observe a real
problem though. The scenario begins by importing a USD file needing a
Mesh Sequence Cache modifier and then attaching a particle system (like
Hair) to the object. This will trigger the specific check calling into
`can_use_mesh_for_orco_evaluation` with the wrong time.
This makes the code path more explicit and passes in the correct time to
USD regardless now e.g. frame 28 vs time 1.166666666666667 (24fps)
Pull Request: https://projects.blender.org/blender/blender/pulls/140092
It would run into using the same frame twice, looking like "freeze
frames"
Apparently we had a similar issue before, see 3f8ec963e3
Just a PoC to show that this looks like a precision/rounding issue when
getting a "working" `UsdTimeCode`.
In the modifier code, we are doing a roundtrip going from frame >> time
(in seconds -- via `BKE_cachefile_time_offset`) and then back to frame
before we store that in `USDMeshReadParams`.
To avoid the precision loss, this PR introduces
`BKE_cachefile_frame_offset` to stay in the "frame" domain and
circumvent going through FPS alltogether.
There might be better ways to let USD handle the "sightly off"
`UsdTimeCode` better though.

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.

The goal is to be able to reuse parts of this code in all the places that call
Geometry Nodes. Currently, that's only a modifier and an operator. More places
may follow in the future though.
This patch does not implement any of the code-reuse yet, it just extracts the
code into a separate file. Follow-up patches will work towards better
code-reuse.
Note, this extracts the entire modifier drawing, including error messages,
baking etc. I found this to be easier, because they still often share a common
core (like getting the logged data).

Nowadays, Geometry Nodes is not only evaluated by a modifier, but also by an
operator and in the future potentially by brushes. Therefore, the old name was
misleading because it sounded like it was specific to the modifier.

This is used as base class for the compute contexts for group and evaluate
closure nodes. Furthermore, in the future this can be used for the compute
context that is passed into field evaluation.

The main goal of this patch is that the column widths and ordering is not reset
every time one switches between different contexts.
It does that by keeping track of multiple `SpreadsheetTable`. There is one for
each table that is viewed (so e.g. the point and edge domain of the same mesh
are two different tables). Each table has an identifier and an array of columns.
There is some garbage collection in place so that the number of stored tables
does not increase unbounded.
This also comes with an updated Python API:
```python
import bpy
spreadsheet = bpy.context.screen.areas[...].spaces.active
active_table = spreadsheet.tables.active
print(active_table.id.type)
print(active_table.id.attribute_domain)
print(active_table.columns[0].id.name)
```
In the future, we might add some smarter logic to keep tables with different
identifiers more in sync. We don't have a great heuristic for that yet.

Previously, when a socket was detected to be unused, it was just grayed out.
This patch adds support for automatically hiding unused sockets based on this
convention: Menu inputs control visibility while other inputs only control
whether something is grayed out.
More specifically, an input is visible if any of these conditions is met:
* It affects the output currently.
* It never affects the output. In this case its usage does not depend on any
menu input.
* It is used if all non-menu inputs are considered to be unknown.
In the future, we could support customizing which inputs are allowed to control
visibility. For now it's good to use the convention that Blender generally
follows itself.
As before, panels are grayed out if they only contain grayed out sockets and
panels are hidden when they don't contain any visible sockets.
Hiding inputs works in group nodes, the Geometry Nodes modifier and node
operators. In theory it will work for all node tree types, but since only
Geometry Nodes supports the Menu Switch node currently, this patch currently
only makes a difference there.
The implementation reuses the existing `SocketUsageInferencer` with a different
sets of inputs. So no new core-inferencing logic was needed.

This converts the public `uiItemFullO` function to an object oriented
API (an `uiLayout::op` overload), matching recents changes in the API.
Changes includes the removal of the paramether `IDProperty *properties`
that seems unused (all places just sets `nullptr`, can be added as last
argument with `nullptr` as default value though), and instead of using a
return paramether the function now returns the pointer to write properties.

Previously, whenever the zone detection algorithm could not find a result, zones
were just not drawn at all. This can be very confusing because it's not
necessarily obvious that something is wrong in this case.
Now, invalid zones and links that made them invalid have an error.
Note, we can't generally detect the "valid part" of zones when there are invalid
links, because it's ambiguous which links are valid. However, the solution here
is to remember the last valid zones, and to look at which links would invalidate
those. Since the zone-detection results in runtime-only data currently, the
error won't show when reopening the file for now.
Implementation wise, this works by keeping a potentially outdated version of the
last valid zones around, even when the zone detection failed. For that to work,
I had to change some node pointers to node identifiers in the zone structs, so
that it is safe to access them even if the nodes have been removed.

This PR intends to replace the current face corner normals calculation.
Compared to the existing code it has a few benefits:
- It's much easier to understand.
- It doesn't require edges, ideally helping to remove them from caches
and eventually to make them optional.
- It is completely multithreaded using the vert to face map, which is
already used for vertex normals and domain interpolation. The previous
code has a significant single threaded portion that scales with the
size of the mesh.
- Lower peak memory usage: It doesn't require a temporary edge to corner
map, the corner to face map, or a corner domain sized bit vector.
- The code sorting corners around a vertex should be easy to reuse.
- It's over twice as fast. On a test file with custom normals I observe
an overall FPS increase of 2.56x, from 37 to 95.

Previously, the modifier name was used to identify it in a compute context or
viewer path. Using `ModifierData.persistent_uid` (which was only introduced
later) has two main benefits: * It is stable even when the modifier name
changes. * It's cheaper and easier to work with since it's just an integer
instead of a string.
Note: Pinned viewer nodes will need to be re-pinned after the change.

Work around an issue with expanded menus that exists for a long time
already. I briefly tried fixing it, but does not seem straight forward unfortunately
without breaking stuff.
Also see the comment in `ui_item_enum_expand_exec`.
This merges the public `uiItemS` and `uiItemS_ex` functions into an
object oriented API (`uiLayout::separator`), matching the python API.
This reduces the difference between the C++ API with the python version,
its also helps while converting code from python to C++ code
(or vice-versa), making it almost seamless.

The old name `modifier_panel_end` was not great because:
* There is no corresponding `*_begin`.
* It sounds more magical then it really is (it just draws the error message).
* It doesn't even have to be at the end as is sometimes the case when there are subpanels.

This converts the public `uiItemO` function to an object oriented
API (`uiLayout::op`).
Also this rearranges `idname` paramether, since this the only one
required, and to make format similar to `uiItemFullO`
Note: One of the benefits of moving from a public function to class
method is to reduce API usage difference between C++ and Python. In
Python this method is called `UILayout::operator`, however `operator`
is a reserved keyword in C++.

Starting with C++20, `fmt::format` will process the format string at
compile time by default. We need to opt out in the cases where this is
not possible by using `fmt::runtime(...)`, like, for example, when using
our various translation utilities.
This mirrors prior commit e62aa986b2 and
fixes 2 cases that have slipped back in.
