refactor: do not try rfl in mkEqnTypes in WF.mkEqns (#4047) 
when dealing with well-founded recursive definitions, `tryURefl` isn't
going to be that useful and possibly slow. So disable that code path
when doing well-founded recursion.

(This is a variant of #4025 where I tried using `with_reducible` to
limit the impact of slow unfolding, but if we can get away with
disabling it complete, then even better.)
