d3d12_platform: ensure windows.h macros don't cause compile errors

The windows.h macros were undefined only at the end of this platform
header previously but with the addition of d3d12sdklayers.h the
definition of ID3D12DebugQueue::GetMessage picked up the macro and
became GetMessageA or GetMessageW, but Dawn code referred to it as
GetMessage causing a compilation error.

Fix this by preemptively loading windows.h and undefing some of the
macros so that the D3D12 headers don't see them.

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 on Windows 10
    • Metal on macOS and iOS
    • Vulkan on Windows, Linux, ChromeOS, Android and Fuchsia
    • OpenGL as best effort where available
  • A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
