Remove non-Sandy UI

Summary:
This removes the Non-Sandy UI from the Flipper codebase. It is a pretty rough scan for unused components, over time when converting more advanced components to Ant design probably even more code can be removed.

Partially used `npx ts-purge` to reveal never imported source files.

Changelog: It is no longer possible to opt out of the new Sandy UI
