Remove XR canvas dirtying step.
Alan tells me that this is no longer necessary, and it causes layout operations to appear in immersive mode profiles when there should not be any.
Remove GL->d3d blit in HoloLens immersive mode
Depends on:
* https://github.com/servo/surfman/pull/151
* https://github.com/asajeffrey/surfman-chains/pull/7
* https://github.com/servo/webxr/pull/133
These changes add two extra APIs for embedders to use when registering a WebXR device - one to allow running any closure as a task in the webgl thread, and one to register an arbitrary surface provider for a particular webxr session. When an openxr session is started, it can then obtain the webgl thread's d3d device from that thread's surfman device and ensure that openxr uses it.
Surface providers are traits that have their methods invoked by the webgl thread as part of the the normal swapchain operations. This allows the openxr surface provider to return surfaces that wrap the underlying openxr textures, which are valid in the webgl thread and can be used as the target of an opaque framebuffer.

Add VTTRegion and part of VTTCue DOM interfaces
<!-- Please describe your changes on the following line: -->
Hello! In this PR I implemented the VTTRegion DOM interface and part of VTTCue (#22312). Before continuing I thought it's maybe a good idea to first request a review or even merge what I did up to this point, as I might get stuck on the next part. I have a slight idea of what needs to be done (I assume it's hooking the GStreamer parser somewhere in `GetCueAsHTML()`), but a short outline or some more instructions would help a lot.
I updated test expectations by first running:
```
./mach test-wpt tests/wpt/web-platform-tests/webvtt/api --log-raw servo.log --pref dom.webvtt.enabled=true
```
then
```
./mach update-wpt servo.log
```
Thanks!

Stop embedder calls and fake rAF when window not visible
This addresses 2 issues:
- a rAF loop might still be ongoing when the window is invisible if script decided that the rAF were going too fast (spurious rAF)
- a hidden window does not run the rAF loop, but the embedder would still be in animating mode

We now go through <Root<MaybeUnreflectedDom<T>>>::reflect_with,
to decrease the amount of bad stuff we can end up doing. This
avoids a source of vtable pointer instability that could cause
issues down the road.

Improved the WebGL2 framebuffer render validation
It seems `MissingColorAttachment` should be returned only when all of the color attachments are missing.
