Auto merge of #25850 - szeged:wgpu_lib_cleanup, r=jdm

Fixing some style related issues in WebGPU.

Changed the Requests/Response from tuples to named struct variants and also sorted in alphabetical order.
Replaced the ID generator functions from `globalscope` with a single function, which returns a `RefMut` and can call the appropriate method to generate resource IDs.
