Back out "Genalize focus/blur behavior in JS" (facebook#53979)

Summary:
Pull Request resolved: facebook#53979

This reverts a previous change that modified how focus behavior is handled in JavaScript. That change caused hierarchy rows to no longer be focusable, either manually or programmatically as they were before, which in turn broke arrow key navigation in entity lists. Reverting the change restores the expected focus behavior and re-enables proper arrow key functionality within entity lists.

Changelog: [Internal]
