[lib/native/web] refactor notif permission alert info reducer

Summary:
This diff refactors the notif permission alert info reducer => alert info reducer. Aside from just renaming the reducer, the reducer now returns an AlertStore instead of just an AlertInfo

Please note this diff + subsequent diffs won't be landed until the migration diff which will be introduced here shortly
