Replace calls to NodeManager::mkSkolem with SkolemManager::mkDummySkolem (#6291)
This is in preparation for refactoring skolem creation throughout the code base to improve proofs and migrate Theory::expandDefinitions to Rewriter::expandDefinitions.
This PR also eliminates some unused code in TheoryArithPrivate.
Followup PRs will start formalizing/eliminating calls to mkDummySkolem.
