Break runtime cycle between VirtualizedList and VirtualizedListContext

Summary:
Breaks the runtime dependency cycle introduced in D40259791 (facebook@9715993) by converting a value import to a type import. (Unlike runtime dependency cycles, type-level cycles are OK as long as they are reasonably small.)

Changelog:
[General][Fixed] - Fix require cycle warning in VirtualizedList
