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.
