1. Fix short circuit detection for basis translator (#12899) …

   The BasisTranslator transpiler pass has a check at the very start that
   is designed to return fast if there is nothing to translate; in
   other words if the instructions in the circuit are already a subset of
   instructions supported by the target. This avoid doing a lot of
   unecessary work to determine this later during the operation of the
   pass. However, this check was not correctly constructed because of a
   type mismatch and would only ever get triggered if the input circuit was
   empty. The source basis is collected as a `Set[Tuple[str, int]]` where
   each tuple is the name and num of qubits for each operation in the
   circuit. While the target basis is just a `Set[str]` for the names
   supported on the target. This mismatch caused the subset check to never
   return True unless it was empty thereby bypassing the intent of the
   short circuit path. This commit fixes the logic by constructing a
   temporary set of just the source names to evaluate whether we should
   return early or not.
