DXC: assert if a flag is unhandled

This avoids issues such as the one I recently fixed, where we were
setting D3DCOMPILE_SKIP_OPTIMIZATION, but this wasn't being handled in
the backend.

Also, since DXC's default opt level is /O3, but we are using the FXC
macros, where the default is /O1, make sure to explicitly set /O3 when
using DXC. This ensures that we _can_ use /O1 in the future by setting
D3DCOMPILE_OPTIMIZATION_LEVEL1.

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.
