Ben Clayton d59cedb5a5 Add tint::Program as a wrapper of tint::ast::Module.
`tint::Program` will become the new public API object for a parsed shader program.
For now, have Program be a simple wrapper around ast::Module so we can migrate Dawn's use of the public tint API.

Add new Program variants of public APIs for places that returned or took a Module.

Remove Reset() methods from Generators, they aren't used, and make the migration harder.
