PTAL! It doesn't add creation of the external texture as that's still super implementation specific, but this will unblock folks that want to use ExternalTexture in WASM (they can import a C object from a precreated JS GPUExternalTexture).
The webgpu.h diff is slightly messy because the new chained struct force a small reordering. The additions themselves should be pretty trivial and they add a chained struct for the equivalent Rust enum option in wgpu.
I chose
ExternalTextureBindingLayoutto match theBuffer/Sampler/...BindingLayoutconvention that's already used forBindGroupLayoutEntrymembers.ExternalTextureBindingEntryis just following that. But I'm not to attached to the exact names.
