MDEV-25477 Auto-create breaks replication when triggering event was not replicated

If UPDATE/DELETE does not change data it is skipped from
replication. We now force replication of such events when they trigger
partition auto-creation.

For ROLLBACK it is as simple as set OPTION_KEEP_LOG
flag. trans_cannot_safely_rollback() does the rest.

For UPDATE/DELETE .. LIMIT 0 we make additional binlog_query() calls
at the early points of return.

As a safety measure we also convert row format into statement if it is
needed. The condition is decided by
binlog_need_stmt_format(). Basically if there are some row events in
cache we don't need that: table open of row event will trigger
auto-creation anyway.

Multi-update/delete works via mysql_select(). There is no early points
of return, so binlogging is always checked by
send_eof()/abort_resultset(). But we must comply with the above
measure of converting into statement.
