The UIDartState is now always owned by the isolate and always freed in the isolate cleanup callback. In the isolate shutdown callback, if the isolate being shut down is the main isolate, the RuntimeController is informed which in turn notifies the RuntimeHolder and thus the ApplicationControllerImpl. The ApplicationControllerImpl tears down the whole Flutter application. This fixes Fuchsia bug: MI4-328
