[ASTERIXDB-2184] Add Immutable DiskBTree

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

Details:
- Add a immutable DiskBTree to for LSM disk components. This DiskBTree
only supports two operations, i.e., search and bulkload. No concurrency
control is performed at all, since it's immutable.
- Change LSMBTree/InvertedIndex to use this DiskBTree
- Add a DiskBTree point search cursor to optimize point lookups
