Add DAWN_USE_WINDOWS_UI option for Zig & MinGW compilers

In Mach engine, we're compiling Dawn using Zig as a C/C++
compiler. Zig provides it's own libc implementation, build
system, and system headers.

Dawn today makes use of newer `windows.ui.*.h` headers introduced in
more recent Windows versions. However, Zig relies on MinGW for it's
system headers and it is not straightforward/desirable to use the
official Windows SDK headers: Zig does not have these headers today.

Since Dawn does not truly require these headers, we are using a
preprocessor directive `DAWN_USE_WINDOWS_UI` to disable this functionality
and enable compilation of Dawn with Zig/MinGW compilers.

I have based the implementation on the existing `DAWN_USE_X11` and
`DAWN_USE_WAYLAND` build configuration approaches.

Dawn's logo: a sun rising behind a stylized mountain inspired by the WebGPU logo. The text Dawn is written below it.

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.
