Revert webrender upgrade
These commits revert the webrender and font-related updates from #27207. This will unbreak our FxR nightly builds while we continue to investigate the underlying crash in ANGLE. Unfortunately it also returns us to the status quo of broken canvas text rendering on UWP, but there's no way to upgrade font-kit without any of the other crates because of the underlying freetype dependency changes that happened.
Fixes#27492.

UWP Crash reporter
This is supposed to address #27167 and #26523. Also fix#27435.
These changes are still WIP as I found a few bugs, it needs more testing and the actual code to upload is not implemented yet. But I'd like to get an early feedback.
First, panics are caught via `panic::set_hook` instead of `catch_unwind` allowing us to catch more panics.
We also now report panics reported via the `Embedder:Panic` message.
Once the panic is caught, if possible, we try to recover.
I haven't found a way to recover when the panic is caught is a non-GL thread. We need a generic way to throw from the UWP code, and even trying to add a UnhandledEvent handler doesn't appear to work.
Once a panic is caught (even if we can not recover) a crash-report file is created, including the backtrace, stdout, and the current url.
If the app did not crash at that point, or after a restart if it did, we check if the crash report file is present, and if so, we present a panel to the user to allow them to upload the report. At that point the user can also add details to the report.

Refactor and improve GPUErrorScopes
- Remove use of equivalent BGLs
- Capture errors from more `Createxxx` operations
- Address crashes on macOS in #27402
Improved ErrorScope model attempts to-
1. Identify and report `OutOfMemoryError` separately.
1. Match `GPUErrorFilter` and pass on uncaptured errors to parent scope.

Don't delete GL textures created by WebXR
<!-- Please describe your changes on the following line: -->
Currently WebGL assumes it owns any WebGLTexture, and deletes the backing GL texture when the object is GC'd. This isn't valid for textures created by a webxr layer manager, which can result in textures being used after they're deleted.

Layout 2020: Implement `clip: rect`
This implements `clip: rect`
Unfortunately, none of the tests pass yet, they are all broken due to https://github.com/servo/servo/issues/27387
Additionally, currently `clip` does not seem to clip the element itself, only its children. I'm not quite sure what to do about that, I patterned this off of the code in the layout 2013 which handled clip immediately after scroll overflow.
