MDL-46214 event: Support deprecation of events
This patch adds two new functions to the event base to allow deprecation of
the individual events, without entirely removing them from the UI.
This is different to our normal deprecation procedure because all events
must support display of historical data. It must also be possible to view
the event information in the event monitor.
