Current CpuExceptionHanderLibNull instance returns EFI_SUCCESS for all three services. If platform does not want to hook the Exception vector for some modules (For example DxeCore), it could select this NULL instance in DSC file for those module. But some modules that want to consume RegisterCpuInterruptHandler() cannot use NULL instance. If platform does not select the correct library instance, it will does work. But the caller does not recognize it. This update is to return EFI_UNSUPPORTED on RegisterCpuInterruptHandler() in NULL instance instead of return EFI_SUCCESS. Once platform selects this NULL instance, the caller could know it from return status.
