Increment the stat_rdb_saves counter in SAVE command (#10827)

Currently, we only increment stat_rdb_saves in rdbSaveBackground,
we should also increment it in the SAVE command.

We concluded there's no need to increment when:
1. saving a base file for an AOF
2. when saving an empty rdb file to delete an old one
3. when saving to sockets (not creating a persistence / snapshot file)

The stat counter was introduced in #10178

* fix a wrong comment in startSaving
