Merge branch 'master' into xr-controller-support

Fix controller model loading for no stb image

Cleanup

- Use doxygen style comments
- Improve comment for XR region type
- Improve RNA descriptions for XR nav location/rotation/scale
- Split controller draw callback into separate model and aim functions

Remove old TinyGLTF files

Merge branch 'master' into xr-controller-support

Update with changes from D10948, D12472

Merge branch 'master' into xr-controller-support

Update based on D10948

Merge branch 'master' into xr-controller-support

Remove XrSessionState.reset_navigation() RNA func

Function was unnecessary since XrSessionState.reset_to_base_pose()
will also reset navigation deltas.

Merge branch 'master' into xr-controller-support

XR: Add reset navigation operator

Resets XR navigation deltas relative to session base pose. Primarily
useful for undoing elevation/scale changes. Will be added to the
default VR actions.

XR: Replace invoke/modal_3d for XR operators

Special 3D-to-2D handling (as invoke/modal_3d is used for) is not
necessary for regular XR operators, so they can use the normal
invoke/modal callbacks.

Cleanup: remove unused struct member, null checks

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".

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.

Cleanup: remove unnecessary #ifdefs

Merge branch 'master' into xr-controller-support

XR: Fix controller model world transforms

Fixes incorrect display of Reverb G2 controller model/animated parts.

Thanks to Werner Trunk for help with debugging.
