ASL version-based validation of required and unexpected fields, part 1

Asl objects were decoupled from AslMarshallable because not all Asl objects follow the same pattern. Also added version mapping logic, which maps a version number to the required or recognized fields for that version for each object. These can be updated as needed as future versions are released.
