We already allow sending closures (if immutable via sharing otherwise via copying). This CL makes use of this to allow the argument to `Isolate.spawn()` to be any closure. Similar to normal message sending, the spawn will fail if the closure cannot be sent (or causes an error on the new isolate, e.g. rehashing error).
