Add a check for scrollEnabled to VirtualizedList error (facebook#34560)

Summary:
Nested `VirtualizedList` is now an [error](facebook@646605b), instead of a warning. Issues [here](facebook#31697) and [here](facebook#33024) outline the concern.

## Changelog

[General] [Added] - Added a check to if `scrollEnabled` is not false, if so then fire the `VirtualizedList` error

Pull Request resolved: facebook#34560

Test Plan: Passes all provided automatic tests. In a personal app, there is a situation of nested ScrollViews that had triggered the error. After defining `scrollEnabled={false}` and adding the check, the error no longer appears.
