Add support for WebGL2 ReadPixels functions
Adds support for the new ReadPixels functions introduced with WebGL2 and the relevant PixelStorei parameters..
Reference: https://www.khronos.org/registry/webgl/specs/latest/2.0/#3.7.10
<!-- Please describe your changes on the following line: -->

This is a work in progress patch, but I think it might be ready for comments. There are a few issues left:
- When the target is the pixel pack buffer, the GL function expects a byte offset as a pointer. In Sparkle the `read_pixels` functions return/work on top of arrays, so for now I've made a [workaround patch](45d8bb263d). I wonder if that's okay or should we do it somehow differently?
- When writing to the pixel pack buffer, padding bytes on the destination are properly ignored. When writing to client buffers, Sparkle `read_pixels` returns a buffer with 1 byte alignment, which I think is fine (less stuff to move between threads), but requires positioning the rows manually (see the bottom of `read_pixels_into` vs. `ReadPixels_`).
- There are some duplicated code between the array buffer and pixel pack buffer variants, eg. the detection of intersection with the framebuffer. This could be refactored, but that results in a function with `Result<Option<Rect<u32>>, WebGLError>`, which I'm not sure is readable enough to help.
- There is a duplication with the WebGL1 code. WebGL2 introduces row length, skip pixels and skip rows as pixel pack parameters which affect the ReadPixels operation. The helper functions could be moved to be usable in WebGL1, but then these new modifiers would also need to be passed as a function parameter, which is somewhat ugly (but would work). What's your opinion about this?

Fix unloading, active BC, and clearing js runtime
<!-- Please describe your changes on the following line: -->
Do not set the window to be the currently active one for the windowproxy as part of `load`, as it will be done later when the document activity is set. And doing it later means that when unload runs, it is with the unloaded pipeline as the active window.
Only nullify the window proxy if it's not used by another (currently-active) window.

Enable webxr by default
This changes two things:
* enable WebXR by default, since it's not exactly an experimental technology in Servo anymore
* enable the glwindow webxr backend by default so it's easier to test WebXR on desktop nightlies
Since the glwindow pref is only checked in the glutin desktop port, enabling it for other ports does not hurt us at all and it removes a papercut for testing WebXR content on desktop.

Set response mime_type based on Content-Type
<!-- Please describe your changes on the following line: -->
Set the response's `mime_type` based on its `Content-Type` header whenever `Response::set_headers` is called. This ensures that `mime_type` is always consistent with `Content-Type`. The other reason for going with this approach is it relies on `extract_mime_type`: afbcbf75ea/components/script/dom/headers.rs (L260-L261)
Besides the consistency argument, I also expect that we'll update the `extract_mime_type` method to conform with its specification.
Another option I explored was adding a `set_mime_type` member to `Response` and calling that with the mime type from `Metadata::content_type` in `FetchResponseListener::process_response`. I decided against this since it expanded the interface of `Response` and didn't have the same benefits of the first option.
Fixes#24628.
