Service to emit the status code in SMM.
The EFI_SMM_STATUS_CODE_PROTOCOL.ReportStatusCode() function enables a driver
to emit a status code while in SMM. 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_SMM_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.
