[Idea: ScrollView] Add getScrollResponder to ScrollView for composition

Browse Source 
Summary:
This is a proposal to add `getScrollResponder` to all ScrollView-like components, including ListView. This allows multiple higher-order scroll views to be composed while allowing the owner of the top-level scroll view to call `scrollableView.getScrollResponder().scrollTo(...)` regardless of whether `scrollableView` is a ScrollView, ListView, InvertedScrollView, etc.
Closes https://github.com/facebook/react-native/pull/766
