fix(gs/achilles): Get rid of universalization step r/2295
The step of "universalizing" function expressions was conflicting with
top-level ascriptions for polymorphic function declarations:
universalization generates universal type variables, and top-level
polymorphic ascription *also* generates universal type variables, and
the two were conflicting with each other when unifying. Let's just get
rid of this now, and we can bring it back in a more principled manner
once we do actual let-generalization (which there's still an ignored
test case for)
