fix(*): make sure elaborator and type_checker use the same "rules" for treating opaque definitions

This is a big change because we have to store in constraints whether we can use the "relaxed" rules or not.
The "relaxed" case says that when type checking the value of an opaque definition we can treat other opaque definitions in the same module as transparent.
