Stephen Gutekanst 9514098b31 dawn/native/d3d12: improve constexpr compatability with clang 
In Mach engine we compile Dawn's d3d12 backend using Zig as a C/C++
compiler, effectively clang with MinGW windows headers. Unfortunately,
this `static constexpr` fails to compile:

```
error: constexpr variable 'kD3D12PromotableReadOnlyStates' must be initialized by a constant expression
```

As kangz previously noted, the reason appears to be because `D3D12_RESOURCE_STATE_COPY_SOURCE`
is not `constexpr` [in MinGW headers](1de9cc347d/mingw-w64-headers/include/winnt.h (L682)).
The thought process is that making this just `const` is fine because
constant propagation would make it a constant anyway.

If we're comfortable merging this, it'd be one less change we have to
maintain on our side - and probably no impact otherwise. On the other
hand, I understand the most-correct fix would be in MinGW headers
themselves. I'd love to land this change, but it's no big deal if you
prefer not.

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
  • Tint is a compiler for the WebGPU Shader Language (WGSL).
