Provide a method to easily provide initial props to a ReactAndroid application 

Summary:
Adds back support for initial props in ReactAndroid while maintaining the abstraction benefits of having the details of ReactActivity abstracted from the end user's MainActivity. This does remove the need for ReactRootView's two paramater version of the overloaded startReactApplication as far as I can tell but I wasn't sure if anyone might be using that method internally.
Closes https://github.com/facebook/react-native/pull/5384
