  Service to emit the status code in MM.

  The EFI_MM_STATUS_CODE_PROTOCOL.ReportStatusCode() function enables a driver
  to emit a status code while in MM.  The reason that there is a separate protocol definition from the
  DXE variant of this service is that the publisher of this protocol will provide a service that is
  capability of coexisting with a foreground operational environment, such as an operating system
  after the termination of boot services.

  @param[in] This                Points to this instance of the EFI_MM_STATUS_CODE_PROTOCOL.
  @param[in] CodeType            DIndicates the type of status code being reported.
  @param[in] Value               Describes the current status of a hardware or software entity.
  @param[in] Instance            The enumeration of a hardware or software entity within the system.
  @param[in] CallerId            This optional parameter may be used to identify the caller.
  @param[in] Data                This optional parameter may be used to pass additional data.

  @retval EFI_SUCCESS            The function completed successfully.
  @retval EFI_INVALID_PARAMETER  The function should not be completed due to a device error.
