Remove old Calendar and Messaging partial/full sync stages (#15380)

Now that all existing and new workspaces have the following syncStage:
- CALENDAR_EVENT_LIST_FETCH_PENDING
- MESSAGE_LIST_FETCH_PENDING

We can fully deprecate the old FULL_CALENDAR_EVENT_LIST_FETCH_PENDING
and PARTIAL_CALENDAR_EVENT_LIST_FETCH_PENDING (full vs partial is now
directly inferred from the presence of a cursor)
