Allow playing video/webm on Windows
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
This makes video/webm play on non-UWP Windows. I couldn't find the equivalent gstmatroska.dll on our GStreamer binaries for UWP.

It's impossible to conditionally use a crate based only on cargo features, so
temporarily disable the backend on all Windows builds while we sort out how
to get the UWP builds working again.
Various UWP GStreamer improvements
There are a number of positive changes in these commits:
* we successfully load GStreamer plugins in ARM64 UWP builds
* we correctly link the ARM64 ANGLE libraries when appropriate
* it is no longer necessary to manually set the LIB environment variable on Windows
* we automatically download and link against UWP-friendly GStreamer binaries when building with `--uwp`
* the use of vcruntime140.dll, msvcp140.dll and api-ms-win-crt-runtime-l1-1-0.dll in the UWP application has been removed and the build does not repackage them
* the set of base supporting GStreamer DLLs has been expanded to allow the gstlibav plugin to load correctly

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.
Adjust gstreamer plugins for UWP.
This excludes a set of plugins and dependencies that are currently built with MinGW and will therefore cause WACK errors. The resulting set of plugins loaded by the UWP app are still not UWP-clean, but this makes it much easier to switch over to UWP-clean binaries in the future.
These changes also allow the HoloLens 2 app to start and load again after #23712.

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.

Support WebAudio on Windows
These changes improve the GStreamer experience on Windows in several ways:
* we package the set of plugins and their dependencies that Servo requires for media support
* we explicitly load those plugins when starting the media engine rather than relying on an existing gstreamer installation
These changes do not affect the experience on non-Windows platforms, but the path is clear to do so in order to fix problems like #23519. With these changes I can successfully hear a tone when loading https://joshmatthews.net/osc.html in both a desktop build and a UWP build.

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.
Note: The WheelEvent interface supports rotation in all 3 spatial
dimensions. This implementation only supports two due to limitations
in the Glutin compositor.
The wheelevent interface is a dom interface that triggers for any
attached device that can rotate in one or more spatial dimensions.
Traditionally this is the mouse wheel though other devices could be
used as well. E.g. the trackball on a trackball mouse.
