Summary:
Nested scrolling in scrollViews, listViews and flatLists are enabled on iOS by default, but needs to be enabled manually on Android. This PR introduces a `nestedScrollEnabled` property to ScrollViews to support nested scrolling on Android 21 and above.
Enabling nested scroll will resolve issues with coordinator layout in android and required to support a collapsing toolbar.
Tested on the test app. We are also using this property in our app currently to support scrolling behaviour required by coordinator layouts.
