Add ClearLog support for the Redfish Event Log Service

This change adds support for the LogService.ClearLog action to
clear the Redfish Event Log.

Tested:
   1. Added entries to the EventLog
   2. Sent the ClearLog action using Postman:
      /redfish/v1/Systems/system/LogServices/EventLog/Actions/LogService.ClearLog
   3. Confirmed that the EventLog was empty
   4. Added entries to the EventLog
   5. Confirmed that the new entries logged successfully
