Coq: refactoring of mathcomp packages (#86088)
- fixed bignum version - fixed coq-bits version - fixed coqprime version - fixed mathcomp and mathcomp extra packages (reworked building scheme and removed unused ssreflect directory) - giving the user access to function filterCoqPackages, because overrideScope' does not re-apply it.
