Prebuild React and React-Native dependencies

In order to improve build times we could extract react and react-native depdencies into DLL and provide a way for user to add their own depednecies to this bundle. However, this solution will split code into 2 files, so unless there’s an option to load multiple filesin RN app, we can’t benefit from it.

There’s an ongoing effort to bring multi-bundle support to RN and Haul already allows to generate multiple bunndles, so this issue is irrelevant. Once we get to more usable state, the docs will have more info on the topic.
