The normals were not allocated before the brush code starts, which is
necessary to store the initial normals in the undo step, among other
things. Previously normals were calculated as part of building the PBVH.
That doesn't make sense anymore because that process shouldn't change
the mesh. For now just add the recalculation in a code path called by
`BKE_sculpt_update_object_for_edit`, called at the beginning of each
stroke, and other places.
I've done this a few times and would have benefited from a utility
function for it, apparently it's done in a few more places too. The
utilities aren't multithreaded for now, it doesn't seem important
and often multithreading happens at a different level of the call
stack anyway.

Implements setting the armature parent and generating
vertex groups for the bones in the armature.
Note: This does not implement the `Envelope` or `Automatic Weights` options.

Current the automasking code stores temporary data as geometry
attributes (except for multires where that doesn't work) in order to
persist the cached factors for cavity and occlusion accross multiple
strokes. However, the benefits of this aren't clear, compared to
improving the performance of these calculations. It's also the last
usage of the sculpt attribute API which we plan to remove. The system
is also hard to understand, to make a more solid cache of automasking
values it would be better to start from scratch.
This commit removes the sculpt attribute API and the automasking stroke
ID system, and moves the cached factors to be cached per stroke rather
than more permanently.

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.
Previously, mapping old to new items was O(n^2) because each new item was
compared to all old items until the corresponding one was found. This patch
introduces a pre-filter to the old elements that have to be checked. Instead of
comparing all old items, only the ones with the same label are compared now.
This reduces the time complexity to O(n), making the tree view much more
usable with many items.
Add the ability to control whether or not Hardware Ray Tracing (HWRT)
is enabled during render tests.
This is done by adding `-RT` to the end of the device name in the
Cycles device list. E.g. `HIP-RT`. This is supported with HIP, oneAPI,
and Metal.
Change in behaviour:
If you do not specify `-RT`, then HWRT will be disabled. This results
in a change in behaviour:
1. `METAL` device tests on M3 or newer Macs no longer using MetalRT
2. `ONEAPI` device tests no longer use Embree GPU.
Note: Some tests are failing on some platforms/configurations that can
now be easily tested due to this commit. This does not effect the
build bot automated testing as it does not test these configurations.
These tests have not been blocked from running, primarily to help
developers investigate and fix the issues.

Joining many geometries was O(n^2) because of deduplication of the same
components was not done using a map. My test file that generates 1000
stars in a repeat zone got 10x faster, but it's possible to create a file for any
speedup.
This adds support for line separators in nodes. Currently this is only available for
built-in nodes and it's only used in the Simulation Zone. However, we also want
to use it in the For Each Geometry Element zone (#127331). Support for node groups
can be added separately too.

Grease Pencil armature deformation has to use the correct
`vertex_group_names` list from the `Curves` (i.e. drawings) rather than
the names from its parent `GreasePencil` data block.
The ancient armature deformation code used a `defbase` list (`ListBase`
of type `bDeformGroup`) from the object via `BKE_id_defgroup_list_get`.
This function does not have enough information to determine the correct
vertex groups for GPv3, and it's use inside supposedly generic code is
highly questionable.
This patch removes the `defbase` lookup inside
`armature_deform_coords_impl` and instead passes an explicit list of
vertex group names to be used for resolving indices. We already have
context in every place this is called to determine the correct vertex
groups, without having to make assumptions down the line based on just
the object type.

As a generic type for referencing the active/initial vertex, int is
more convenient here because mostly it's used for array indexing,
and moving from int to `BMVert` and `SubdivCCGCoord` is
simple and cheap.
Properly track Action and Slot assignment when entering/exiting NLA
tweak mode.
This doesn't properly sync the length of the NLA strip when exiting
tweak mode. This and more NLA work is tracked at #127489.

Deforming motion blurred point clouds do not render in Cycles
HIP-RT when BVH timesteps != 0 if Blender is launched with
debug memory.
The root cause is that the size of allocated memory for the
bounding boxes is reported to HIP-RT not the number of valid
bounding boxes.

VDB files would fail to render in HIP-RT because NanoVDB wasn't
enabled when compiling HIP-RT kernels, resulting in NanoVDB textures
not being sampled and a blank result being returned instead.
The fix is to enable NanoVDB when compiling HIP-RT kernels.

Fix the unnecessary recreation of the denoiser that occurs if
Cycles had fallen back to an alternative denoiser in a previous
interation. (E.g. Fallback from OptiX to OIDN)
This issue occured because Cycles didn't understand that when it
previously setup the denoising device, that it had fallen back to
something else. So it thinks the denoising settings have been changes
and tries to recreate the denoiser.
The solution is to first compute the settings change due to
the fallback, then check to see if it's different from the current
denoiser, then recreate the denoiser device if neccesary.

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.
On Windows, if compiler is 32 bit there already is a fatal error. If it
is 64 bit (normal case, and any case when build can actually work), it
feels like "64 bit compiler detected" status message does not indicate
anything useful.

Do not try to kill thumbnail generation job when destroying the cache
(which happens as part of destroying the scene) -- all the code
paths that destroy a scene already cancel outstanding WM jobs. And WM
itself might be gone at that point, so accessing a stale pointer to it
can lead to a crash.
Instead, fix the problem of "refresh sequencer can cause a crash" by
not destroying the thumbnail cache, but merely clearing it in
sequencer_refresh_all_exec.

The same random number was used for sampling color channel at each step,
which leads to bias. Fixed by rescaling the random number.
Another possibility would be to scramble `rng_offset` and use a new
random number each time, similar as in subsurface scattering, but
rescaling random number should be faster than computing a new one, and
is favorable here since the precision here is not very important

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.

Add an RNA function that can log the users of an Action Slot. It's
available in debug builds only, as it is purely a debug tool for C++
developers at the moment.
Eventually it's likely that the list of Action Slot users will be
exposed to RNA/Python directly, but I'll only write code for that once
we actually need it for non-debugging functionality. For now this is
enough.
Select handles of strip available below the cursor when
`selection.seq1/seq2` exists in `sequencer_box_select_invoke`.
Also fixed the condition in `sequencer_main_cursor` so the new
WM_CURSOR_HANDLE is visible.
