[silgen] Change two places we used Builtin.Executor to instead use Optional<any Actor> as an expected executor.
We want SILGen to have a simplified view of its executor and know that whenever one sees an Actor, it is an actual actor instead of a Builtin.Executor. This just simplifies code. Also, we should eventually have an invariant that Builtin.Executor should only be allowed in LoweredSIL after LowerHopToExecutor has run. But that is a change for another day.
