oem-ampere: eventManager: Handle DIMM and DDR status sensor event
This commit adds the handler and needed APIs to handle DIMM and DDR
status event as Numeric Sensor Event in Ampere's OemEventManager class.
The handler will decode the event data, parse them to readable info and
log to Redfish Event Log.
