This adds support for showing various stats of volume grids in the spreadsheet:
* Extent: Number of voxels in each direction of the bounding box of the grid.
* Voxels: Total number of active voxels in the grid. This includes all voxels
which are stored in tiles (e.g. one leaf tile contains 512 voxels).
* Leaf Voxels: Number of active voxels stored in leaf nodes. This does not
contain any voxels that are part of tiles.
* Tiles: Number of active tiles in the grid.
* Size: Estimated size of the volume grid in memory.
All these stats are cached on the volume grid now. A new `tag_tree_changed`
method has been added to invalidate the cache. Computing these stats is not
cheap (but not more than a few ms even for large grids). That mainly means that
we can't do it for socket inspection because that would cause too much overhead.
However, doing it just for the grids that are currently visible in the
spreadsheet seems fine and useful.
This also adds some general improvements to the spreadsheet:
* Support `int64_t` and `int3` columns.
* Draw ints with thousand separators.
* Support showing ints as number of bytes such as `23 MB`.

Very similar to the layer name search added somewhat recently.
This just displays the names of existing grids in the "Name"
inputs to the Store and Get Named Grid nodes.

`append and reuse` is chosen as default in DNA but this enumpropertyitem
isn't added to the array when `Non data block packing` is disabled in
Developer tools (see `rna_preference_asset_libray_import_method_itemf`).
To fix this, change default in DNA to `ASSET_IMPORT_PACK`. In case of
"non packing", change import_method inside `asset_library_add()`
function. Also introduce `rna_preference_asset_libray_import_method_default`
so that "reset to default value" operator works correctly.

!146956 introduced buffer streaming and is used to improve the
performance of text rendering. However the solution didn't check the
minimum allowed offset for storage buffers.
This PR will use the correct offset. This was only visible on Qualcomm
devices as other systems don't limit this offset.

Where possible, inline sockets when the input and output are both the
image or the same value just transformed.
Even though it may make sense, do not apply this change in cases where
the image is the same when a factor is set to "0". For example the
Alpha Over node, where the "Background" matches the "Image" output if
factor is 0. Or the Mix node's "A" and "Image".
Also hide the value (usually a full white color input widget).
It makes for a more compact UI, less noise, and it matches a similar
layout in Geometry Nodes.
See PR for screenshots.

The general idea is to order all menus as:
```
Common categories
(e.g. Input/output)
---
Specific categories
---
Assets
--
Common categories
(e.g. Group/Layout)
```
## Changes:
### Compositor
- Removed Color/Mix submenu
- Moved Vector to Utilities
- New Category: "Creative". This is where most new assets will fit in.
- Moved to Creative:
- Kuwahara
- Pixelate
- Posterize
### Geo Nodes
- Moved 'Vector' to 'Utilities'
- Moved 'Attribute' before 'Geometry'
- Moved 'Material' to 'Geometry'
- Moved 'Color' to top level, grouped with Utilities
### Shader
- Moved 'Vector' to 'Utilities'
- Deleted 'Converter'
- New 'Displacement' menu
- Grouped 'Color' with Utilities (remains top level)

Use the current Action API (i.e. move away from the to-be-deleted-in-5.0
one) to import and export F-Curves from/to FBX files.
There is a slight difference in functionality for the exporter, in the
selection of which Actions to export for the "All Actions" option. This
is just a minimal change to ensure the legacy API is no longer used.
Old: `action.fcurves` was iterated, and if all FCurves could resolve to
existing properties, the Action was exported. This would only work
reliably for single-slotted Actions, due to the use of the deprecated
`action.fcurves` property.
New: the above check is done for each Channelbag in the Action. The
first Channelbag that match the above check is exported. This does _not_
export all suitable channelbags; it merely improves on the old behaviour
slightly.

This adds versioning code that replaces any timeline with a
dopesheet where the footer is shown, AND it removes the
timeline from the menu options.
If the area is too small to show both, the footer and the
header then only the footer is shown.
This assumes that users created the small timeline
just for the playback controls
Any uses of `SACTCONT_TIMELINE` (except for versioning) have been removed.

`ui_numedit_but_NUM` only uses the "reduced" `fac` from `ui_do_but_NUM`
in case the button is a float button.
So to clarify that in the UI, dont display the "Precision" in the

Part of a fix for #145877 which exposed multiple crashes in the
outliner.
Hide depsgraph collections that are dynamically allocated,
causing access to freed memory form the outliner.
Ref !145955
The SVG icon outline could be over 1.0 when hovering over icons in the
outliner. This was converted to bytes and set FontBLF::shadow_color[3]
which overflowed the byte range.
Clamp the alpha before passing to BLF SVG drawing.
This is because `snap_obj_fn` checks `SnapObjectParams` `edit_mode_type`
for not being `SNAP_GEOM_FINAL` even if the curve is not in editmode.
Probably an oversight in [0] which changed this for
`nearest_world_object_fn` and `raycast_obj_fn` (but not `snap_obj_fn`).
The reason it worked in non-XRay-shading mode is that another codepath
is taken then (`raycastObjects` instead of `snapObjectsRay` where this
is not an issue -- the then used `raycast_obj_fn` had the correct check
already, see above).

The check to draw transform constraints was returning too early and
skipping the later check for the `V3D_HIDE_OVERLAYS` flag.
This meant that transform constraints (e.g. when moving over X axis)
were always shown even when all overlays were turned off, which can
be very distracting.
Fix it by switching the check, so it returns false if the region is
not the same, but continues happily if it is.
See PR for details and screenshots.

For a period of time during 4.2~4.3, the `UvSculpt` settings could have

prevent odd behavior and removes the old versioning code.

The purpose of this node is to create a grid with new voxel values on
the same grid topology as an existing grid. The new values are the
result of field evaluation. Multiple grids can be created at the same
time, so that intermediate results used for multiple grids can be
efficiently reused during evaluation. This is more efficient than the
"Volume Cube" node, for instance, because the output grid shares the
sparseness of the input topology grid.

Collection side is trivial, Object one is a bit more intricate, as
its LightLinking data behave similar to AnimData of IDs, which requires
a custom liboverride `apply` callback.

The zone add operator necessarily has to add the input and output nodes
separately one at a time. After the first node is added a tree update is
executed, but the zone is incomplete and the runtime update will temporarily
remove all zones until the second node is added. Using zone lookup without
checking the pointer will crash in this state.

Ensure that function which requires evaluated depsgraph does get
such a depsgraph.
The BKE_scene_ensure_depsgraph() is not guaranteed to give evaluated
depsgraph, it only ensures that the depsgraph exists for the given
combination of bmain, scene, and view layer.

In 113d91aba8 the mesh joining operator is
largely rewritten but the `join_positions_and_shape_keys` part didn't
supply valid `bmain` and `id` for `BKE_key_add` which leads to crash.
Now fixed by supplying correct arguments.

Crash seems to happen due to parallelized access of data in liboverride
diffing code (presumably when a same linked data is used as reference
for several local liboverrides?).
Since there is zero reason to actually create IDGroup properties there
(it's actually fairly bad, also adding useless overhead and trash data
in system IDProperties), add a new API to access a Pointer PropertyRNA,
`RNA_property_pointer_get_never_create`, which ensures that the call
never creates data, and simply returns `PointerRNA_NULL` instead.
Also reverts abd683fcb5 and re-enable liboverride unittests.
NOTE: This only addresses the case from the report, the current behavior
of `RNA_property_pointer_get` is simply wrong and needs to be rethought.
This is not a simple change though most likely. See also #147072.

The motivation is to keep backward compatibility after deprecating
`material.use_nodes()` and `world.use_nodes`. For example the
following script would behave the same way in 4.5 and 5.0:
```python
mat = bpy.data.materials.new("My new mat")
mat.use_nodes = True
```
