Cleanup: minor simplification to status allocation

Geometry Nodes: fix z-up spline normal calculation

Previously it didn't work when the tangents were collinear to the z axis.

Fix pose-mode statistics with multi-object editing

- Include all objects in pose mode.
- Show the number of objects in pose mode.
- Show the number of objects in edit mode for all types of objects
(not just meshes).

Geometry Nodes: Separate Components Node

Implementation of T86970. This node takes a geometry input with
multiple components and outputs them by component type. Meshes,
Curves, and Point Clouds support combining multiple input instances,
while volumes will only output the first volume component input until
suitable instance realization for multiple volumes is finished.

When direct geometry instancing is implemented it will be possible to
avoid realizing instances in this node.

Fix: Image node alpha socket converted to operations twice

On selecting a multi-layer image with a combined pass, a "Combined"
socket is created and default combined pass socket "Image" is
disabled by setting `SOCK_UNAVAIL` flag. When converting into
operations, `ImageNode` converts alpha socket on finding any socket with
a combined pass without checking the flag.

Since commit rB93e2491ee724 an assertion fails when mapping sockets
twice because now map `add_new` is used.

Screen: simplify internal logic for new full-screen areas

Creating a new full screen area had it's area initialized as empty,
updating the screen then set the area to a 3D view (as a fallback),
before the actual area type was set.

This made setting the intended space-type run the 3D views exit callback
on a 3D view without a View3D struct allocated, which the exit callback
needed to account for.

Resolve by calling ED_screen_change after the area type has been set.

Alembic procedural: support reading per-vertex UV sets

This adds support for importing UV sets which are defined per vertex,
instead of per face corners. Such UV sets can be generated when the
mesh is split according to UV islands, or when there is only one UV
island, in which cases only a single UV value can be stored per
vertex since vertices will never be on a seam.

Cleanup: reduce warnings when compiling release builds.

Compositor: Full frame RGB node

Cleanup: unused warning

Cleanup: Add files for version independent versioning helpers

Adds `source/blender/blendloader/intern/versioning_common.cc` and
`versioning_common.h` for version independent versioning functions.

I only placed `do_versions_add_region_if_not_found()` in there for now.
`blo_do_version_old_trackto_to_constraints()` could also be added, but
that's so old, I prefer keeping that in `versioning_legacy.c`.

UI: Support right aligned non-shortcut hints in widgets

Widget drawing code already supported drawing right-aligned, grayed out
shortcut strings. This patch generalizes things a bit so this can also
be used to draw other hints in the same way. There have been a few
instances in the past where this would've been useful, D11046 being the
latest one.

Note that besides some manual regression testing, I didn't check if this
works yet, as there is no code actually using it (other than the
shortcuts). Can be checked as part of further development for D11046.

A possible further improvement would be providing a way to define how
clipping should be done. E.g. sometimes the right-aligned text should be
clipped first (because it's just a hint), in other cases it should be
left untouched (like current code explicitly does it for shortcuts).

Removes the `UI_BUT_HAS_SHORTCUT` flag, which isn't needed anymore.

DRW: sanitize 'DRW_mesh_batch_cache_dirty_tag'

Create maps that specify which batches have vbo or ibo as a reference
and use these maps to discard batches along with buffers.

Geometry Nodes: Allow int attribute input fields with single value

Just like the way we often have a choice between an attribute input and
a single float, this adds the ability to choose between attribute and
integer input sockets, useful for D11421.

Cleanup: Fix inconsistent parameter name warning

VSE: Improve animation evaluation performance

Use lookup string callback function for `sequences_all` RNA property
`rna_SequenceEditor_sequences_all_lookup_string` using a GHash for faster lookups.

When names are changed or strips are added/removed the lookup is tagged invalid.
The next time the lookup is used it will rebuild it.

Fix T88263: Incorrect image offset from old file

Versioning code for converting strip offset property doesn't work, when
property was animated and disabled or when crop was used.

When offset property is animated and offset is enabled, animation is
converted to be used with new transform design. When offset is disabled,
animation is left untouched. New transform design doesn't have option
to disable offset, and therefore old unconverted animation is used
instead of converted static value.

Remove animation from propery if it was unused.

Another issue was that both X and Y offset animation was being corrected
by factor caluclated for X channel.

BLI: use explicit task isolation, no longer part of parallel operations

After looking into task isolation issues with Sergey, we couldn't find the
reason behind the deadlocks that we are getting in T87938 and a Sprite Fright
file involving motion blur renders.

There is no apparent place where we adding or waiting on tasks in a task group
from different isolation regions, which is what is known to cause problems. Yet
it still hangs. Either we do not understand some limitation of TBB isolation,
or there is a bug in TBB, but we could not figure it out.

Instead the idea is to use isolation only where we know we need it: when
holding a mutex lock and then doing some multithreaded operation within that
locked region. Three places where we do this now:
* Generated images
* Cached BVH tree building
* OpenVDB lazy grid loading

Compared to the more automatic approach previously used, there is the downside
that it is easy to miss places where we need isolation. Yet doing it more
automatically is also causing unexpected issue and bugs that we found no
solution for, so this seems better.

Patch implemented by Sergey and me.
