MDEV-31776 Online ALTER reports the number of affected rows incorrectly

Browse Source 
Add a new virtual function that will increase the inserted rows count
for the insert log event and decrease it for the delete event.

Reuses Rows_log_event::m_row_count on the replication side, which was only
set on the logging side.
