writer: Move sanitizers into the backends

Adds a new single-function API for the generators, which applies the
sanitizing transform and performs the generation in one step, and
returns a result object which contains the generated code and success
status/diagnostics.

The new APIs take an `Option` structure to control backend-specific
generation details (e.g. MSL fixed sample mask). The result objects
also provide backend-specific feedback (e.g. whether a UBO of buffer
lengths was generated).

HLSL needs a list of entry points to validate, and it's the HLSL
sanitizer that generates an entry point for programs that do not have
one. This change makes the HLSL generator return the list of
post-sanitize entry points so that the Tint executable can forward
them to the validation code.
