Unshared heap size excluding data calculation is broken

Details

    Description

      Unshared heap size excluding data calculation is broken.

      For example, it does not takes into consideration whether the buffers are on-heap or off-heap - empty offheap buffer is 64-bytes while empty heap buffer is 48-bytes.

      It matters especially when we have offheap buffers-based memtables.
