This routine takes a synchronous non-throwing main actor isolated closure without a result. If we are dynamically on the main actor, we just run the closure synchronously. Otherwise, we run a new task on the main actor and call the closure on that. This builds on top of the previous commit by using swift_task_isCurrentExecutorWithFlags in the implementation of this function. To backwards deploy this function on Darwin, I used some tricks from libdispatch to validate that we are on the main queue.
