tint: Add `enable_abstract_numerics` flag on Resolver

When enabled, unsuffixed literals will be treated as abstract numerics.
By having this disabled by default, we can build up the tests without
the risk of breaking production code.

This flag is enabled for resolver unit tests. This can safely be done
with no change in tested behavior, as all tests use the '_i' or '_u'
literal suffixes, so currently there are no tests that exercise abstract
numerics.

Bug: tint:1504

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).
