Remove support for auto-paging of cursors.

Auto-paging of cursors is being removed in favor of a support lib component.
Rationale:
    1) Auto-paging as implemented has potential to negatively impact system health.
    2) Similar functionality w/o system health concerns can be provided
       specific to RecyclerView.

Test: Removed. CTS coverage updated.
