Replication of MyISAM and Aria DML is experimental and best
effort only. Earlier change make INSERT SELECT on both
MyISAM and Aria to replicate using TOI and STATEMENT
replication. Replication should happen only if user
has set needed wsrep_mode setting.
Note: This commit contains additional changes compared
to those already made for the 10.5 branch.
+ small refactoring after main fix.

Problem was too tight condition on ha_commit_trans to not
allow non transactional storage engines participate 2pc
in Galera case. This is required because transaction
using e.g. procedures might read mysql.proc table inside
a trasaction and these tables use at the moment Aria
storage engine that does not support 2pc.
Fixed by allowing read only transactions to storage
engines that do not support two phase commit to participate
2pc transaction. These will be committed later separately.

Problem was that REPLACE was using consistency check that started
TOI and we tried to rollback it.
Do not use wsrep_before_rollback and wsrep_after_rollback if
we are runing consistency check because no writeset keys are
in that case added. Do not allow consistency check usage
if table storage for target table is not InnoDB, instead
give warning. REPLACE|SELECT INTO ... SELECT will use
now TOI if table storage for target table is not InnoDB
to maintain consistency between galera nodes.
