Summary:
A common UI pattern for list empty states is some text/images centered inside the visible part of the list. This is pretty hard to do currently because we wrap ListEmptyComponent with an extra view with no way to style it so we cannot just use `flex: 1` to make it fill the available space.
- Added an example of ListEmptyComponent in the FlatList example in RNTester
Before (no way to make ListEmptyComponent fill the space):

- Tested some edge cases like returning null from the ListEmptyComponent
- Tested in an app that uses FlatList + ListEmptyComponent
[GENERAL] [MINOR] [VirtualizedList] - Don't wrap ListEmptyComponent in an extra view
