V9 Virtualizer Draft

• Code is up-to-date with the master branch
• Your changes are covered by tests (if possible) - basic tests for unstable to ensure virtualization is working.
• You've run yarn change locally

Current Behavior

Currently, Virtualization is provided by several OSS libraries that enable scroll detection and positioning of components, these libraries, while excellent, do not adhere to the same design philosophy as V9 in terms of composability and user access.

New Behavior

This Virtualizer is intended to be a composable, generic wrapper for long-length children with minimal DOM changes, it uses the intersection observer library to optimize and remove scroll callback loops and instead only initiate calculations and re-renders when required.

This library can be used vertically or horizontally, in regular or reverse order, is compatible with generic types and a multitude of List, Grid, or Table implementations. If you wish to provide a scroll view, the ref may be passed in to optimize further, however it is not required.
