Added CHOOSE operator for sets (#4211)
This PR enables THEORY_UF by default for sets and adds the operator CHOOSE for sets which returns an element from a given set. The semantics is as follows:
If a set A = {x}, then the term (choose A) is equivalent to the term x.
If the set is empty, then (choose A) is an arbitrary value.
If the set has cardinality > 1, then (choose A) will deterministically return an element in A.
