[tint][resolver] Add UnresolvedIdentifier, IncompleteType

Have Resolver::Identifier() resolve the ast::Identifier to
UnresolvedIdentifier instead of immediately erroring. This is then used
by the outer expression / statement to provide the error message, which
can be more specific. This also allows us to remove the
'identifier_resolve_hint_' member.

Have Resolver::Identifier() resolve to IncompleteType for types
that expect a template argument, but were not provided one. This is
handled by Resolver::Call() for the inferred constructors, e.g 'vec3',
'mat2x4' and 'array'. This reduces the amount of duplicated code between
the two methods.

Both of these changes are required to make resolving of type
non-recursive.

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.
