Break runtime cycle between VirtualizedList and VirtualizedListContext

Summary:
Breaks the runtime dependency cycle introduced in D40259791 (https://github.com/facebook/react-native/commit/971599317b7bdf1152157206f9503a23ac8c4162) 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
