Implement hidden PK for RBR of no-unique key table

Details

    Description

      Performance of row event applying on no-unique key table is inferior and degrades
      with growing size of the table.
      This task aims at replacement of table scanning with key lookup, and such key - or a hidden "PK" - would be created
      automatically. It may not be visible to the user as a part of the table def like the row id of Innodb is never exposed.
