Move ErrorScopes implementation into wgpu-core

Description
As outlined in #8911 (comment) in this PR we only move implementation of error scopes into wgpu-core. Errors are currently still produced by consumers (wgpu, deno, ...) and pushed onto device via handle_error and co. The error design is taken from wgpu, but handling somewhat different (wgpu has special handling for panicking situations and uses indexes to check for out-of-order drops so for the time being wgpu still has own implementation of push and pop but now using the stack from wgc). For wgpu we now use ParentDevice::device from wgc and send error in there.

I managed to get deno changes to minimum, but the most complication is using events from wgc for device lost and uncaptured device error as we need Send/Sync for types we bring in closures. So we use ArcMutex https://docs.rs/deno_inside/latest/deno_inside/struct.V8CrossThreadTaskSpawner.html and pass other non-send/sync stuff via hashmap via state.

Testing
Should be covered by existing tests.

Squash or Rebase?

Rebase.

Checklist

• I self-reviewed and fully understand this PR.
• WebGPU implementations built with wgpu may be affected behaviorally.

@sagudev could you fixup the 2 commits? I can also merge as is if there are conflicts since they do already compile individually.

I am not sure what you are asking me to do. All commits should be good to go (they pass CI independently) and github does not report any conflicts to me. Should I rebase?

[teoxoy]

There are 2 commits named "Move error types to wgpu-types", I thought you wanted to squash the 2nd into the first but there might be conflicts. Also "use cross thread spawn and store the data in state" could be squashed into "[deno] Use error impl from core".

[sagudev]

I did rebase and cleaned up commits.

Thanks!

Anything else blocking landing this?

Oh, no - I was waiting on that job that kept intermittently failing to succeed.
