Added metrics update for `deleteRange` operation (`numKeysOnWritingVersion`
and `numInternalKeysOnWritingVersion`). The metric update is gated on
`conf.trackTotalNumberOfRows` so callers that don't expose the metric pay no
extra cost.
### Why are the changes needed?
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.
-->
`deleteRange` currently does not update the row-count metrics, which can
leave `numKeysOnWritingVersion` and `numInternalKeysOnWritingVersion`
inaccurate after range deletes. This change keeps the metrics consistent with
other write paths while avoiding extra cost when `trackTotalNumberOfRows` is
disabled.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Four new unit tests in `RocksDBStateStoreSuite`:
- numKeys metric is decremented by the number of keys removed
- empty range does not change numKeys metric
- internal column family keys are tracked separately
- metric is not updated when trackTotalNumberOfRows is disabled
