Mark SharedTextureMemory stable for DXGI and IOSurface

This feature is not supported over the wire, meaning that it is not
possible for Chromium renderer processes to use it. Hence it is not a
problem to mark it stable so that the Chromium GPU-side internal
implementation can assume that it is present. This will allow removing
usage of the WrapIOSurface() API from Chromium, which in turn will
allow cleanly optimizing the IOSurface implementation of
SharedTextureMemory.

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.
