MB-72548: Cache root document count in segment snapshot (#2351)

- `DocCount` API obtains the current root snapshot, and calls
`CountRoot` on all the segment snapshots.
- The segment snapshots contain the immutable deleted bitmap and segment
base, so each time we call the `CountRoot` API on the segment snapshots,
we end up calculating the same value each time.
- This is because zapx API iterates through the deleted bitmap for each
API call.
- Fix this issue by caching the count root value at the segment
snapshot.
