Support running WebGL in its own thread or on the main thread.
This is the final missing piece to support WebGL in ANGLE on Windows. ANGLE doesn't support multiple GL contexts on separate threads using the same underlying Direct3d device, so we need to process all GL operations for WebGL on the same thread as the compositor. These changes try to retain enough flexibility to support both approaches so we can get WebGL working on Windows ASAP.

There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
Get the glwindow test XR device to share a GL context with WebGL
<!-- Please describe your changes on the following line: -->
Get glutin windows able to open new windows which share GL textures. This is used by the webxr glwindow test device.

Remove canvas->compositing dependency
There's one tiny place in the canvas crate that depends on the compositing crate, and it's really quite backwards. If we use trait objects instead it becomes much cleaner to reason about.

Upgrade WebRender
This is against an old Servo because I can't build current Servo due to compile errors in RNG crates. I verified that it starts up.

Use new WebXR API in script
Todo:
- [x] Hook new `Frame` information into `XRFrame`
- [x] Make spaces use new transform info
- [x] Hook up session view metadata correctly
- [x] Get mocking working again
- [x] Get inputs working
Optional todos:
- [x] Add support for active and animationFrame bool on XRFrame
- [x] Correctly handle viewer and offset spaces instead of casting
- [x] Error on zero-length quaternions
<s>Not really ready for review yet, but you can go ahead and review what I have so far. It doesn't do anything yet, aside from crash horribly. I'm opening this PR early so i have a place to track progress.</s>

Media player rendering with GL textures
These patches pass the application's OpenGL raw context and the its native display address to the media player, in order to create an internal wrapped context, thus it will generate video frames as textures.
For now only EGL from glutin-based app and android are in place, though tested only in Linux glutin app.
This PR also renders the generated frame textures by Servo/Media and renders them by using a thread that connects Webrenderer's ExternalImageHandler and each instantiated player. **By now, these patches, disable the WebGL rendering**. We need to provide a ExternalImageHandler demuxer.
This PR depends on https://github.com/servo/media/pull/270
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- This PR fixes#22300 and fixes#22920
In order to test it you must launch servo as
`./mach run -- --pref media.glvideo.enabled [...]`

This module adds a structure (WindowGLContext) which holds the
OpenGL parameters that are going to be used by servo-media player
to render video frames using OpenGL.
In order to fill this structure, three new methods were added to
WindowMethods trait. In this patch only the Glutin-based
implementation provides a simple boilerplate.
The WindowGLContext is created in the entry point of libservo, when
the application window is created, and later passed to the
constellation, the pipeline and to the window element in dom, thus
htmlmediaelement has a mean to obtain these parameters via its
window.
Add UWP port - bis
This is #23658 with some fixes:
- removed nspr from DLL dependencies (was breaking VS build)
- exclude symbols from header file (was breaking VS build)
- rebased
Before merging:
- please check the rebased commit that introduces the `--uwp` option (things moved around since 7c85dc09b5)
- should we wait until the WR fix lands upstream?
