Reland "[dawn][common] Adds MutexProtectedSupport CRTP wrapper."

This is a reland of commit 1e23f1ca224b164294be79b02417174f39ecfb6b

- Uses raw_ptr instead of reference in Guard because d3d11 extends
  the templates and with a reference, we lose the ability to null
  out the object to prevent destructors from running on an object
  that should otherwise have been moved.

Original change's description:
> [dawn][common] Adds MutexProtectedSupport CRTP wrapper.
>
> - Adds a CRTP wrapper that can be used to both declare a
>   MutexProtected struct and its internals. This is particularly
>   useful when we want to provide additional backdoors to read
>   data without acquiring the lock.
> - Adds relevant tests for the new wrapper.
> - Also makes Guards hold a reference instead of a pointer since
>   the pointer should never be null anyways.

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.
