[ASTERIXDB-3003][STO] Enable batch point lookups and stateful cursors

- user model changes: yes
- storage format changes: no
- interface changes: yes

Details:
- Allow the user to enable stateful and batch point lookups
- A compiler flag 'compiler.batch.lookup' can be set to enable
  batch and stateful point-lookups
- The stateful cursors are used to search for subsequent points
  without the need for searching the BTree's interior nodes for
  each point lookup
- The cursor is kept open, and the page is pinned until:
  - the page is consumed (i.e., no more points can be found in the page)
  - or the cursor is closed
- Introduce IDiskBTreeStatefulPointSearchCursor interface for different
  DiskBTree implementations
