MDEV-30378 Versioned REPLACE succeeds with ON DELETE RESTRICT constraint

node->is_delete was incorrectly set to NO_DELETE for a set of operations.

In general we shouldn't rely on sql_command and look for more abstract ways
to control the behavior.

trg_event_map seems to be a suitable way. To mind replica nodes, it is ORed
with slave_fk_event_map, which stores trg_event_map when replica has
triggers disabled.
