PSA: Minor additions to WebGPU

[Corentin Wallez]

Hey all,

We are doing two minor additions to WebGPU that we believe have zero compatibility risk:

• The addition of "rgb10a2uint" as a GPUTextureFormat. This format was forgotten by the WebGPU group when making the initial list of GPUTextureFormats. Both WebKit and Firefox were in favor of adding it during the WebGPU meeting.
• The enablement of the "float32-filterable" optional feature. Likewise it was easily agreed to in the WebGPU group, see minutes.

Cheers,

Corentin

Presumably these are developer-expose changes. Can you please file an Intent-to-prototype-and-ship for them?
