MASTER_GTID_WAIT to work for replicated galera GTIDS

To solve the ability to handle a replication delay (async or galera) in a variety of replication topologies, without an application needing to know the topology (beyond reader/writer nodes), MASTER_GTID_WAIT should wait for both async and galera GTID replication to be applied.

The WSREP_LAST_WRITTEN_GTID/WSREP_LAST_SEEN_GTID/ WSREP_SYNC_WAIT_UPTO_GTID that got dumped in MariaDB 10.4/ Galera-4 fails to consider async replication topologies exist with Galera or understand the deep frustration in MDEV-20720 nor does it try to correct it (https://github.com/MariaDB/server/pull/1317).
