EventService: Add ResourceEvent registries

This commit adds new files for DMTF resource registry
and corresponding json message definitions.

Tested by:
  1. GET https://${bmc}/redfish/v1/Registries
  2. GET https://${bmc}/redfish/v1/Registries/ResourceEvent
  3. GET https://${bmc}/redfish/v1/Registries/ResourceEvent/ResourceEvent
  4. Redfish Validator passed ( giving out messages as == Severity:
       The given property is deprecated by revision: This property has been deprecated
       in favor of MessageSeverity, which ties the values to the enumerations defined
       for the Health property within Status.)
