feat(library/unifier): postpone as much as possible universe constraints of the form ?m1 =?= max(l1, l2) and ?m1 =?= imax(l1, l2) where ?m1 occurs in the right hand side. When there is nothing else to be done, try to solve them by reducing to ?m1 = l1 and ?m1 = l2.

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.
