Auto merge of #25580 - szeged:wgpu_worker, r=jdm

Support worker for WebGPU

To create resource ids for the WebGPU we need to access the `IdentityHub`.
In order to access the `IdentityHub` from a `Window` or a `Worker` as well, I've moved the `IdentityHub` to the `GlobalScope` from the `Navigator`.
