Fix T80039: Do not subdivide with Multires is mesh has no faces

This skips the subdivision operation if the mesh has no loops, avoiding
the crash.

Fix T80077: Objects disappear when joining with a zero scaled axis

Use invert_m4_m4_safe_ortho when joining objects so zero scaled axis
doesn't cause all points to be scaled to zero.

Instead geometry is left un-scaled on degenerate axes.

Report a warning in this case since users may want to adjust the
active objects scale.

BLI_math_matrix: add invert_m4_m4_safe_ortho (m3 version too)

Unlike invert_m4_m4_safe, this calculates zeroed axes.
Useful when we need to use the inverse of an objects matrix,
keeping the valid axis, only filling in the zeroed ones.

Fix T77359: Crash adding UV's in edit-mode with linked duplicates

This prevents UV layer mix up in
MeshBatchCache.cd_used/cd_needed/cd_used_over_time which depends on the
extraction method.

One object's mesh can be accessed with MR_EXTRACT_MESH, another object
that uses the same mesh can use MR_EXTRACT_BMESH based on
(Object.mode & OB_MODE_EDIT), this causes a problem as the edit-mesh
and the mesh aren't always in sync, the custom data layers wont
necessarily match up, causing T77359.

Fix T79111: Cycles: Image Sequence not rendering

Caused by c7aa0f9d743ee9cafe91b4a51d9f1ecc5e437d71.

Since above commit, BKE_image_user_frame_calc requires an image (not
just the iuser) to get the framenumber.

Cycles used to call this with NULL image (in `image_user_file_path` and
`image_user_frame_number`), now pass the image as well.

Fix T78186: Dyntopo panel error with tools that dont have a brush

Fix critical bug in foreach ID looper of Scene data-block.

Since stone age of lib_query, the code would iterate over the current
list of active sequences (from a meta strip e.g.), and not over the
whole list of those.

This is a critical issue as it means in some cases (editing a meta strip
typically), some ID pointers would be missed/ignored by this foreach
looper, which is now at the center of most of our ID management code.

This caused a bug here at the studio, leading to loss of all sound IDs
used by sound strips when editing and undoing inside a meta strip, since
ID refcounting would not happen properly on strips using sounds outside
the meta-strip context during file reading of the undo steps.

To be backported to 2.83.

Fix T79935: Inonsistent simplify behavior when linking collection with objects in sub-collection.

RNA update function would only update objects from 'main' instantiated
collection, not those from sub-collections.

This should be comitted to 2.90 (and backported to 2.83 too).

Fix warning when compiling on Linux with WITH_XR_OPENXR enabled

Fix constant lighting change in VR view when rotating head

We have to explicitly enable fixed world space lighting. This was in
fact already done, but overridden by the code to sync the 3D View
shading settings to the VR view.

Fix/workaround graphics issues breaking SteamVR use with Blender

Windows only workaround. I'll have to investigate Linux separately.

Steam's OpenGL compatibility is still new and doesn't work for us yet
(neither does it for standard OpenXR examples from what I've heard and
seen myself). We can work around that by falling back to our DirectX
compatibility layer.
Note that this DirectX compatibility still doesn't work for some
systems, see T76082.

Implementation note: Since the graphics binding extensions have to be
enabled before we can find out which runtime is in use (e.g. SteamVR vs.
Oculus, etc), we can now enable multiple graphics binding extensions but
settle for a single one to use later.

Once the SteamVR OpenGL backend works, we can remove this workaround
again.

Fixes T78267.

VR: Properly support outputting sRGB swapchain buffers

Latest SteamVR OpenXR updates brought OpenGL support, but only with sRGB
buffers. I think for DirectX it's the same now.
It's not a big issue for us to use sRGB buffers, so that's what I will
do for now. That way we shouldn't need hardcoded exceptions for specific
runtimes that don't transform linear buffers correctly.
