Switch to new Tint generator API

Tint now has a single-function API for code generation that
automatically runs the backend-specific sanitizer transforms. This API
allows for backend-specific configuration options such as the fixed
sample mask for MSL (and, in the future, information about which
compiler/version is being targeted), and returns any backend-specific
metadata such as whether a UBO of buffer sizes is required by the
shader.

This change prevents the post-sanitizer program from being exposed to
Dawn, which is a potential foot-gun (e.g. the Inspector is not
expected to be run after the sanitizer transforms, and Dawn is
currently doing this).

The old Generator class API will be removed from Tint shortly after
landing this change.

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
