UI: File Browser Options Fix

With D12436 two File Browser properties were renamed but two references
not changed in space_filebrowser.py

See D12449 for details.

Revert "Depsgraph: release GIL when evaluating the depsgraph"

It is causing crashes in rendering, when releasing the GIL in render threads
while the main thread is holding it.

Fix T88755: Reuse Temp Windows by Type not Title

Reuse temporary windows when they share the same single area type, not
because they share the same title.

Geometry Nodes: Allow exposing color sockets to the modifier

This commit allows connecting color sockets to the group input and
changing the input values in the modifier. Before there was an error
since this was more complicated to support with the previous IDProperty

Cleanup: use NODE_SOCKET_API_ARRAY for array sockets

This prevents copying the arrays when setting new values in the sockets.

No functional changes.

XR: Support for Varjo OpenXR extensions

This adds support for two Varjo specific OpenXR vendor extensions:
1) XR_VARJO_QUAD_VIEWS
2) XR_VARJO_FOVEATED_RENDERING

Together these enable human eye resolution rendering on supported
devices (currently mainly Varjo XR-3 and VR-3).

In addition, there's a detection for Varjo OpenXR runtime.

This has been tested on real Varjo XR-3 hardware and Varjo Simulator
and confirmed to function correctly. Foveation works, and the views are
rendered correctly for all the four views.

Depsgraph: release GIL when evaluating the depsgraph

Evaluating the dependency graph potentially executes Python code when
evaluating drivers. In specific situations (see T91046) this could deadlock
Blender entirely. Temporarily releasing the GIL when evaluating the depsgraph
resolves this.

Calling the `BPy_BEGIN_ALLOW_THREADS` macro is relatively safe, as it's
a no-op when the current thread does not have the GIL.

Geometry Nodes: fields and anonymous attributes

This implements the initial core framework for fields and anonymous
attributes (also see T91274).

The new functionality is hidden behind the "Geometry Nodes Fields"
feature flag. When enabled in the user preferences, the following
new nodes become available: `Position`, `Index`, `Normal`,
`Set Position` and `Attribute Capture`.

Socket inspection has not been updated to work with fields yet.

Besides these changes at the user level, this patch contains the
ground work for:
* building and evaluating fields at run-time (`FN_fields.hh`) and
* creating and accessing anonymous attributes on geometry
(`BKE_anonymous_attribute.h`).

For evaluating fields we use a new so called multi-function procedure
(`FN_multi_function_procedure.hh`). It allows composing multi-functions
in arbitrary ways and supports efficient evaluation as is required by
fields. See `FN_multi_function_procedure.hh` for more details on how
this evaluation mechanism can be used.

A new `AttributeIDRef` has been added which allows handling named
and anonymous attributes in the same way in many places.

Hans and I worked on this patch together.

Cleanup: Readfile: cleanup some logic checks.

IDmanagement: makelocal: Fix mistake in recent commit.

rB8cc3d2d6f51f introduced option to force make_local code to either copy
or actually make a linked ID local, but logic of boolean options
handling was broken.

This commit simplifies logic here and fixes the issue.

NOTE: Since those new options were not used yet this was a harmless bug.

Fix FONT objects cannot use Object Font anymore

Mistake in {rB459974896228}.

To use Object Fonts, (vertex) instancing needs to be enabled.
So bring back the instancing panel and improve the instancing choice
(similar to rB6c0c766bcaa0) by just giving the 'Vertex' choice (or
'None') and explain this is only used for Object Fonts on characters.

Was reported in D11348 itself.

Fix typo in BKE_object_as_kdtree

Seems like an oversight in {rB86635402d516}?

Stumbled over this while investigating another report, but this line in
its current form does not make sense (was taking derivedFinal - not
derivedDeform - prior so I assume this has to be
BKE_object_get_evaluated_mesh now).

(it is now only used for vertex parenting where this should not be an
issue, but best keep this generic).

Fix typo checking empty gizmo keymap

Fix smooth-view failure to add mouse-move events

View operations that left the cursor over a gizmo were not being updated
because the mouse-move event was added while the view was animated
instead of once the animation had completed.
Mouse-move events were also missing when smooth-view was disabled.

This fixes a glitch with the 3D view navigation gizmo where multiple
clicks on the view aligned axis failed to switch to the opposite side
unless the user moved the cursor between clicks.
