Various webxr WPT fixes

r? @asajeffrey
Went through most of the failing tests and fixed them. Many of the remaining ones fail due to unsupported features that I can slowly whittle away.
Workaround for #24984 - Solve crashes when panicking / Hang Monitoring by using cargo's patch mechanism to work around a bug in libbacktrace
Temporarly patch backtrace-rs
---
libbacktrace contains an error leading to invalid pointers when trying to backtrace a stacktrace.
These invalid pointers led to a crash, whenever a panic or Hang Monitoring happened (which is where the stack is captured).
Since fixing the issue properly at gcc will require some time, I've created a small and patched version of backtrace-rs, which will be used as patch here.

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.

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`
