Mark SharedTextureMemory/SharedFence as supported on the wire

In Chromium we will need to use SharedTextureMemory/SharedFence on the
server-side for WebGPU devices. To do so we need to add the features on
such devices. However, doing so currently fails because the features
are not listed as wire-supported. This CL changes that to enable this
use case. Note that the features will still not actually be accessible
over the wire as they are tagged as "native" in dawn.json. Thus, this
CL will have the intended effect of allowing usage of these features
*only* from the server side in the context of client-requested Devices.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the WebGPU standard. More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:

  • WebGPU C/C++ headers that applications and other building blocks use.
    • The webgpu.h version that Dawn implements.
    • A C++ wrapper for the webgpu.h.
  • A “native” implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
  • Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
