LGTM - it woul dbe good to have a general mechanism to debounce Dart_NotifyLowMemory and Dart_NotifyDestroyed

From Triage: This is a sound fix but we want to debounce spammy calls to Dart_NotifyDestroyed as a whole in the runtime controller. I suggest patching RuntimeController::NotifyDestroyed in addition to this.

Well, the strategy of performing GC when a FlutterView detaches from the engine is not friendly for scenarios where multiple FlutterViews reuse the same engine, which may slow down the initial display of pages. It would be even better if there is an interface provided to control whether this GC is enabled. :)
