[universes] deprecate constr_of_global

In favor of a constr_of_monomorphic_global function. When people
move to the new Coqlib interface they will also see this deprecation
message encouraging them to think about the best move.

This commit changes a few references to constr_of_global and replaces
them with a constr_of_monomorphic_global which makes it apparent that
this is not the function to call to globalize polymorphic references.

The remaining parts using constr_of_monomorphic_global are easily
identifiable using this: omega, btauto, ring, funind and auto_ind_decl
mainly (this fixes firstorder). What this means is that the symbols
registered for these tactics have to be monomorphic for now.
