Adds APIs for runners to delegate WindowProc handlers into the Flutter engine, and for plugins to register as possible delegates. This allows for plugins to alter top-level window behavior in ways that can only be done from the WindowProc, such as resize control. This functionality remains entirely on the native side, so is synchronous. Part of https://github.com/flutter/flutter/issues/53168
