This is another WebGPU API update, it picks up a lot of changes that were made recently: - new bind group layout - new render pipeline descriptor - new vertex formats - limits - compressed texture formats - index format - query sets - and more small ones! It also brings in the updated `gfx/wgpu` to support these API changes. Differential Revision: https://phabricator.services.mozilla.com/D107013
