[msl] Add support for clip_distances

The clip distances builtin is an array, but needs to be emitted as a
C-style array instead of using Tint's array wrapper. Additionally, the
builtin attribute needs to be emitted after the member name and before
the array count. The easiest way to achieve this is by special-casing
the logic for emitting this struct member in the printer, rather than
inventing a new MSL array type and special-casing the way we emit that
type to include the name and builtin as part of it.

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.
