[native] Add loggedInUserInfo prop to ChatThreadList

Summary:
This diff should be a no-op. In a later diff, we'll need to pass loggedInUserInfo directly to a couple places (getThreadListSearchResults and createPendingThread).

Depends on D6753

Test Plan: Flow, and playing around with inbox on native
