d3d12: Reintroduce DXGI keyed mutex support

Reintroduce DXGI keyed mutex support to the D3D12 backend, except that
the keyed mutex is now acquired in a tight scope around command buffer
execution similar to the D3D11 backend.

A KeyedMutex wrapper is introduced since we need a custom deleter to
dispose the keyed mutex with D3D11on12 and ComPtr doesn't support that.
The wrapper doesn't have a scoped Guard helper because abseil containers
don't yet support transparent comparator/hash functions and we don't
have too many places where we acquire and release the keyed mutex.

The SharedTextureMemory concurrent read test is now enabled on both
D3D11 and D3D12 when using keyed mutex.

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.
