[tint][val] Improve input_index_attachement validation

This is less of a migration, and instead using the ValidateIOAttribute
framework to test for the attribute being on function params and
returns, which are not Vars. The original Var code is retained to
cover MSVs and other cases like function scoped vars.

This involved loosen when ValidatorIOAttributes runs to handle MSVs
that are not in the In or Out address space. This will also be needed
for dealing with binding_point in the future, which is why I went with
a more systematic change instead of just special casing 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.
