d3d: Use EnumAdapterByGpuPreference when available

Dawn currently uses EnumAdapters1 to enumerate IDXGIAdapters, and then
uses various properties of the adapter to infer the power preference.
This change uses the IDXGIFactory6::EnumAdapterByGpuPreference to
correctly return the most accurate power preference order, in
IDXGIFactory6 is available. EnumAdapters1 is used as a fallback. The
order of adapters returned by either API should take priority, so the
manual sorting is Dawn is bypassed for D3D backends.

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.
