MDEV-30645: CREATE TRIGGER FOR { STARTUP | SHUTDOWN }

Follow-up to fix building with EMBEDDED server. Since support of
events isn't compiled in for embedded server but some stuff from
implementation of events is used for support of triggers, common
source code used both for events and triggers was extracted into
the separate files event_common.cc/event_common.h
