Subject: [PATCH] configureScene: add routeStack in second argument

Summary:
Giving routeStack in second parameter of configureScene allows to do more advanced scene configuration.
I have use-case where I can only determine the scene config from the navigation context (not only from the route object but also from where it's located).
Closes https://github.com/facebook/react-native/pull/5254
