Add WGPUFuture, and implement for WorkDone in Metal + wire

This implements the WGPUFuture version of OnSubmittedWorkDone for the
Metal backend, as well as in the wire (over the old implementation).

This is a partial implementation of WGPUFuture. It sits alongside the
old API until it's complete and has all of the breaking API changes
we're going to make. (See bug dawn:2021.)

For more on WGPUFuture, see the design doc in bug dawn:1987.

Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress 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.
