Reduce the time of looking for MLOG_CHECKPOINT during crash recovery

Details

    Description

      We should fix MySQL Bug #80788 in MariaDB 10.2.

      When I made the InnoDB crash recovery more robust by implementing WL#7142, I also introduced an extra redo log scan pass that could be avoided.
      Before MariaDB 10.2 is released as GA, we are free to change the redo log format and add extra information to the redo log checkpoint page, so that the extra scan can be avoided.
