  Report status code to all supported device.

  This function implements EFI_STATUS_CODE_PROTOCOL.ReportStatusCode().
  It calls into the workers which dispatches the platform specific listeners.

  @param  CodeType         Indicates the type of status code being reported.
  @param  Value            Describes the current status of a hardware or software entity.

                           classify the entity as well as an operation.
  @param  Instance         The enumeration of a hardware or software entity within
                           the system. Valid instance numbers start with 1.
  @param  CallerId         This optional parameter may be used to identify the caller.
