Implement GPUUncapturedErrorEvent
<!-- Please describe your changes on the following line: -->
A new `uncapturederror` variant is added to atoms/static-atoms.txt. `GPUUncapturedErrorEvent` is fired when an error is not captured by any `ErrorScope`.
All tests for error scopes `PASS` now.

Update WebGPU CTS to main branch
<!-- Please describe your changes on the following line: -->
`main` branch in https://github.com/gpuweb/cts is closer to our implementation and it makes more sense to use that.

Major fixes in error reporting in GPUCommandEncoder and ErrorScope Model
<!-- Please describe your changes on the following line: -->
1. Update wgpu to use the error model on wgpu-core side. Register error Ids separately.
2. ~~Record errors only in `GPUCommandEncoder.finish()`. Errors are no longer recorded in ErrorScopes in transfer commands or while recording passes. Any errors that occur are stored on the server-side in `error_command_encoders: HashMap<id::CommandEncoderId, String>` and reported on `CommandEncoderFinish`. Note: This should be reverted when the spec gets updated.~~
3. Correct a major flaw in ErrorScope Model. If multiple operations are issued inside scope and an early operation fails, the promise resolves and script execution continues. The scope, however, was not popped until the results of all its operations were received. This meant that if the user issues another operation, it was assumed to be issued in an error scope that has already been popped by the user, which led to the failure of a number of tests. This is solved by storing a `popped` boolean to check whether `popErrorScope()` has been called on a scope or not. Operation is now issued in the lastest scope for which `popped == false`.
One of the tests used to crash, but it no longer does (All subtests under it fail now). That explains the large number of failing test expectations that have been added. Most of them fail due to the tests being outdated. I'll switch to the updated branch in the next PR.

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.

Add a copy of WebGPU CTS to wpt.
<!-- Please describe your changes on the following line: -->
The test suite is generated from `glsl-dependent` branch in https://github.com/gpuweb/cts
We already have 6/44 tests passing and a number of subtests in other tests also pass.
