MDEV-7995 : DMLs not getting replicated with log-bin=OFF & binlog-format != ROW

Browse Source 
This bug is a side-effect of fix for MDEV-6924, where we completely
stopped a statement-based event from getting into the binlog cache when
binary logging is not enabled (and thus, wsrep_emulate_binlog mode = 1).
As a result, the SBR events were not replicated.

Fixed by allowing the SBR events to be written into the binlog cache.

Note: Only DMLs were affected as DDLs are replicated via TOI.

Merged galera_create_trigger.test from github.com/codership/mysql-wsrep.

Even though wsrep only supports ROW binary log format, a user can set
binlog format to STATEMENT (wsrep_forced_binlog_format). In which case
the control might reach here even when binary logging (--log-bin) is
not enabled. This is possible because wsrep patch partially enables
binary logging by setting wsrep_emulate_binlog.
