Fix build warnings

Merge branch 'master' into xr-controller-support

XR: Use dynamic arrays for eye, controller data

Makes API/functionality more adaptable to different systems.

XR: Move controller batch creation to draw func

Ensures that a valid GPU context is available during batch creation,
which fixes potential access violation issues.

XR: Fix for Viewport Denoising Artifacts

Addresses T76003. When using VR with Eevee and viewport denoising,
scene geometry could sometimes be occluded for one eye. Solution is
to use a separate GPUViewport/GPUOffscreen for each VR view instead
of reusing a single one for rendering.

XR: Reference Space Improvements

Improves control over the XR reference space by using the stage ref
space (user-defined tracking bounds) instead of local ref space
(position at application launch), if available. Also adds an
"absolute tracking" session option to skip applying eye offsets that
are normally added for placing users exactly at landmarks.

By enabling absolute tracking, users can define the tracking origin
in a way that is not linked to the headset position. Instead, the
tracking values given by the XR runtime are left unadjusted and a
user can manually calibrate an "origin" landmark object to adjust to
their real world space.

Can be useful for applications that use external tracking systems
and those that primarily only need to use controllers and not the
headset (e.g. motion capture).

The absolute tracking option requires an update to the VR
Scene Inspection addon to be accessible by regular users.
