This aligns Workers and Window and MessagePorts to all use the same mechanism for transferring serialized messages across realms. It also allows transferring more message ports into a worker. Re-enable the Worker-echo test, as none of the MessagePort tests have themselves been flaky, and those are now using the same underlying implementation.
