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.
Implement DOMPoint.fromPoint
<!-- Please describe your changes on the following line: -->
Implements DOMPoint.fromPoint and fixes codegen to use default value when an optional dictionary member got `undefined`.
PS: The codegen change is about:
```webidl
dictionary MyDictionary {
optional short myMember = 0;
short anotherMember;
}
[Exposed=Window, Constructor]
interface MyInterface {
void myMethod(optional MyDictionary myDict);
};
```
```js
// The following two must behave same
new MyInterface().myMethod({ myMember: undefined, anotherMember = 0 });
new MyInterface().myMethod({ anotherMember = 0 });
```

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 [...]`
