MDEV-15393 gtid_slave_pos duplicate key errors after mysqldump restore
When mysqldump is run to dump the `mysql` system database, it generates INSERT statements into the table `mysql.gtid_slave_pos`. After running the backup script those inserts did not produce the expected gtid state on slave. In particular the maximum of mysql.gtid_slave_pos.sub_id did not make into rpl_global_gtid_slave_state.last_sub_id an in-memory object that is supposed to match the current state of the table. And that was regardless of whether --gtid option was specified or not. Later when the backup recipient server starts as slave in *non-gtid* mode this desychronization may lead to a duplicate key error. This effect is corrected for --gtid mode mysqldump/mariadb-dump only as the following. The fixes ensure the insert block of the dump script is followed with a "summing-up" SET @global.gtid_slave_pos assignment. For the implemenation part, note a deferred print-out of SET-gtid_slave_pos and associated comments is prefered over relocating of the entire blocks if (opt_master,slave_data && do_show_master,slave_status) ... because of compatiblity concern. Namely an error inside do_show_*() is handled in the new code the same way, as early as, as before. A regression test can be run in how-to-reproduce mode as well. One affected mtr test observed. rpl_mysqldump_slave.result "mismatch" shows now the new deferring print of SET-gtid_slave_pos policy in action.
