fix: module system: remove WellFounded-specific hacks (#9143) 
This PR removes a rather ugly hack in the module system, exposing the
bodies of theorems whose type mention `WellFounded`.

The original motivation was that reducing well-founded definitions (e.g.
in `by rfl`) requires reducing proofs, so they need to be available.

But reducing proofs is generally fraught with peril, and we have been
nudging our users away from using it for a while, e.g. in #5182. Since
the module system is opt-in and users will gradually migrate to it, it
may be reasonable to expect them to avoid reducing well-founded
recursion in the process

This way we don't need hacks like this (which, without evidence, I
believe would be incomplete anyways) and we get the nice guarantee that
within the module system, theorems bodies are always private.
