Cleanup: return window in 'WM_window_find_under_cursor'

This better matches other functions like `BKE_screen_find_area_xy`.

GPencil: Split poll function to enable only in Edit mode

The asset creation must work only in edit mode, but the import in any mode.

PyAPI: GPU: expose clip distances

Now you can get a shader that uses Clip Planes and set the number of
Clip Distanes with `gpu.state.clip_distances_set(value)`.

Cycles X: Remove tile, FSAA, and save buffers options

FSAA setting was not used by any engine.

The Save Buffers is being replaced with the new tile rendering
in Cycles.

Removing code from Blender side because there is no way we can
guarantee it is working,

Unfortunately, non-official external render engines need to
implement those options on their side. But good news is that
they have more control this way.

Cleanup: Use `ID_IS_LINKED` instead of direct `id.lib` pointer check.

Add locking fallback atomics implementation

Is used for platforms for which we do not have native implementation,
such as MIPS, for example.

It is possible to test locking implementation on local computer by
defining `ATOMIC_FORCE_USE_FALLBACK` in the atomic_ops_unix.h file.

Run full regression suit with the locking implementation on amd64
Linux platform and all tests passed.

Having non-optimal but working implementation for odd-ball platforms
seems to be a better choice than failing the build entirely.

Cleanup: add ATTR_WARN_UNUSED_RESULT to BLI_string_utf8.h

Cleanup: use BLI_UTF8_MAX define

XR: Refactor motion capture objects

This refactors the feature of binding objects to controllers
and recording auto-keyframes, or "motion capture objects", by
providing a more complete API for managing objects and moving the
implementation out of wm_xr_session.c and into its own file
(wm_xr_mocap.c).

In addition, motion capture objects are now stored as a dynamic array
instead of a fixed array, which was previously hard-coded for
specific devices. Each entry in this dynamic array is uniquely
identified by an Object pointer and is mapped to a VR device via an
OpenXR user path. For example, an object can be bound to the headset
via "/user/head", and the left controller via "/user/hand/left".

Decouple highlighted tiles from RenderPart

Should be no visible change on user side.
Preparing for render parts removal as part of Cycles X project.

Fix view3d.toggle_shading() not updating VR view

Reason was that the WM notifier did not set the NS_VIEW3D_SHADING
subtype, which the VR view listens for for a shading update.

In the case of view3d.toggle_xray(), a notifier was absent
altogether.
