Some WPT tests were failing because they expected the body for a
multipart form data response to end with a CRLF. So I updated
encode_multipart_form_data to add the missing terminator.

Ensure SpiderMonkey shuts down cleanly
This is the alternate solution that I described in #24845. Given how much simpler the resulting code is, I'm now much more in favour of this design. Depends on https://github.com/servo/rust-mozjs/pull/487.

Don't panic if surfman initialization fails.
Since WebGL is only one component of the web platform, there's no reason that failing to initialize surfman for webgl support should take down the entire browser.

Implement timer-task-source, time-out service worker
<!-- Please describe your changes on the following line: -->
Implements the timer task-source, and folds the IPC glue-code into a single route set by the globalscope.
Also switches service worker to using a dedicated "time-out" mechanism, which previously relied on the timer mechanism(and I think didn't actually implement script timers).

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?

Initial implementation of WebGPU API
<!-- Please describe your changes on the following line: -->
- Added the WebIDL bindings for GPU and GPUadapter interfaces.
- Created a background thread for WebGPU api calls.
- Established the async communication between the background thread and the WebGPU interfaces.
- Implemented the `requesAdapter` function of `navigator.gpu`
`./mach test-tidy` reports an error due to the different `arrayvec` version used in `servo` and `webgpu`, so added it to the ignore list in `servo-tidy.toml`

Allow build to explicitly set the media stack
<!-- Please describe your changes on the following line: -->
_[This is based on @asajeffrey's work in #23423, and is a rebase and continuation of that branch]_
This allows `./mach build` to override the media stack, which is currently hard-wired based on the target. To skip gstreamer, run `./mach build -d --media-stack=dummy`.

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.
