(proof-new) Clean up uses of witness with skolem lemmas (#6109)
This ensures we do not return WITNESS terms in response to ppRewrite. This makes standard utility methods in SkolemLemma to help make this easy.
It also removes TheorySetsPrivate::expandDefinitions, which was returning WITNESS in response to expandDefinitions, which is no longer permitted.
