[ASTERIXDB-2494][RT] Ensure Dataset Ref Counters Are Thread-safe

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

Details:
- Dataset/Index reference counters are modified concurrently by
  multiple threads and should be thread-safe. Thread-safety issues
  in these counters could result in leaving a dataset allocated
  in memory even though it can be evicted.
