Fix T79146: Sculpt Mode lags until the entire mesh is visible

This was caused when the BKE_pbvh_draw_cb function was used with
update_only_visible set to false. In that case, all nodes with the flag
were updating, but the update flag was only cleared for visible nodes.
This was causing constant updates per redraw in no visible nodes until
they enter the view frustum and their flag was cleared.

In order to fix this and prevent it from happening again:
- Updating the buffers, flushing the updates and clearing the flags are
now part of the same function. It does not make sense to do these in
separate places.

- The BKE_pbvh_draw_cb function was refactored so the
pbvh_update_draw_buffers is only called once. It should now be easier to
understand what the function does when it is used to update only visible
nodes or all nodes.

Fix T78681: "Add Primitive" icons are cropped in tool header

The issue can be simply resolved by moving the primitives and plus
icons slightly. They still bump up against the top and bottom of the
header but it looks much better now.

Cleanup: Reduce variable scope

Fix T83925: Crash when rendering on the CPU with OptiX denoiser enabled

Rendering on the CPU uses the Embree BVH layout, whether the OptiX denoiser is enabled or not.
This means the "build_bvh" function gets a "BVHEmbree" object to fill and not a "BVHMulti" as it
was assuming before, which caused crashes due to memory geting overwritten incorrectly. This
fixes that by redirecting Embree BVH builds to the Embree device.

Cleanup: UndoType: use `size_t` for memory size of structs.

Cleanup: Undo code: `poll` function.

Remove obviously outdated comment, and explictely set `poll` to `NULL`
in the one case it is not actually defined (sculpt undo).

Fix T83915: Subdivision Surface modifier causes visual artifacts in Cycles rendered viewport - CPU and OptiX

Changing the geometry in the current scene caused the primitive offsets for all geometry to
change, but the values would not be updated in all bottom-level BVH structures. Rendering
artifacts and crashes where the result. This fixes that by ensuring all BVH structures are
updated when the primitive offsets change.

Fix T84389: RGB Curves node shows "tone" option outside of compositor

Since the introduction in rB4de7c0c3105a, the option is only used in the
compositor, it has no effect elsewhere [texture nodes, shader nodes].

Now only show the option for the compositor.

Compositor: Alpha Mode

{D9211} introduced pre-multiplying the color for the keying node. This
pre-multiplication should also be done by other keying nodes and should be
the default operation for alpha node.

This patch will change the logic of keying nodes (Cryptomatte Node,
Channel Matte, Chroma Matte, Color Matte, Difference Matte, Distance
Matte, Luminance Matte) and breaks old files.

The Set alpha node has a mode parameter. This parameter changes
the logic to `Apply Mask` the alpha on the RGBA channels of the input color
or only replace the alpha channel (old behavior).

The replace mode is automatically set for older files. When adding
new files the the multiply mode is set.

Fix T84367: Fix crash when showing invalid/legacy constraints

Exposed by rBeaa44afe703e.

Definition for CONSTRAINT_TYPE_NULL is not totally clear (it is set for
constraints without data, see an old comment from Ton), but for these, a
TypeInfo cannot be fetched.

Avoid processing those constraints in UI code, just do nothing instead.

Eevee Cryptomatte: Store hashes in render result meta data

Stores cryptomatte hashes as meta data to the render result. Compositors could

Fix T84053: Mask overlay in image editor not working

The mask overlay wasn't part of the overlay engine. The reasoning nehind
this was that more editors used the mask overlay and most of them used
old drawing code. This patch adds the mask overlay drawing to the draw
overlay engine. This code path will only be used by the image editor
VSE, Compositor and Movie Clip editor will still use the previous
method.

During this patch some alternatives have been researched:
1. `ED_mask_draw_region`: this would lead to different code paths when
drawing in the image editor, and some hacks to retrieve the correct
framebuffer.
2. Add mask drawing to image engine: Would lead to incorrect color
management when viewing the mask.
3. Add mask drawing to image engine and overlay engine: Would lead to
duplicated code.
4. Add mask drawing to overlay engine and for combined overlay select
the correct framebuffer.

Option 4 was chosen as the exception (switching framebuffers) can be
done without hacks. The code stays clean.

Fix T84404: Crash when using Skin Resize in mesh without Skin modifier

Before that commit `TD_SKIP` was marked for all vertices.

Asset browser: workspace in the wrong category

Workspaces [FILTER_ID_WS] were in the `Environment` category
IDFilterBoolean, whereas they are in the `Miscellaneous` category in

(note this was already done in rB2c317457cbf2 for the file browser case)

Sculpt: use distance threshold for dyntopo symmetrize

This was only used for non-dyntopo symmetrize.
There is no reason to use a hard-coded value in this case.

Cleanup: remove UNUSED(..) from public function declarations

This doesn't serve any purpose and can become out of sync
with the function it's self without reporting warnings.
