Dawn: Implement adapter toggles and promote UseDXC as adapter toggle

This CL implement adapter toggles by accepting DawnTogglesDescriptor in
instance.EnumerateAdapters and APIRequestAdapter, and also promote
UseDXC as an adapter toggle. This CL also make adapters report supported
features based on its own toggles state, while validate device required
features using device's toggles state. In this case, a device may
support more features than its adapter reported to support (i.e. those
features enabled by device's overridden toggles).

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.
