Make D3D12 backend robust to the InfoQueue being absent

Previous to this change, the D3D12 backend used IsBackendValidationEnabled
to determine whether the InfoQueue was present and errored out if it
wasn't.

Unfortunately, since the D3D12 debug layer is enabled before D3D12
devices are created and Chromium makes the device before reading the
request, IsBackendValidationEnabled may return true even when the
debug layer is not, in fact, enabled.

Therefore, the D3D12 backend must remain robust to validation enabled
requests and check for itself at device creation time whether it is,
truly enabled.

The D3D11 backend follows a similar pattern.

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.
