Ian McKellar 05751f7be9 Support cleaner Dart isolate shutdown handling. (#4096)
If an isolate shuts down (for example if an app calls
Isolate.current.kill()), the UIDartState* on DartController will refer
to a freed object. This wires through notification that the is shutting
down through to the DartController so it can clean up appropriately.
