elog: add extended management engine event
We are seeing ME disabled and ME error events on some devices and this extended info can help with debug. Also fix a potential issue where if the log does manage to get completely full it will never try to shrink it because the only call to shrink the log happens after a successful event write. Add a check at elog init time to shrink the log size.
