webgpu: Update wgpu and revamp computepass (#32575)

* Do not wait on drop, but rather wake poller thread

* Update wgpu and render stuff

* Set some good expectations

* Update wgpu again

* handle IPC error as warning

* More good expectations

* Some more expectations

CTS does not match the spec: https://github.com/gpuweb/cts/issues/3806

* This expectations are due to other changes in servo

also happening on main

* Explain error_command_encoders and remove RefCell around it

* fixup

* store validness of passes

* More good expectations

* More docs

* this assert is wrong

* This is even more right per CTS/spec

Only Command encoder state errors are allowed here, but wgpu does not exposes them.

* More good expectations

* One bad expectation

* Fix my english
