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.

BLI: support removing multiple elements from a vector

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.
