    Once licensed, switching to a different feature requires a system reboot, notify user about the same.
    
    Details:
    On licensed NMOS setup, if user restarts nvidia-gridd service and
    selected 'GRID Virtual Apps' license edition. There is mismatch in
    licensed feature type enabled in the driver and feature type read from
    gridd.conf/UI control. In this change, notify user that license features
    are still enabled in the driver even if license is released and hence restart is
    required. Set appropriate license status message to indicate the same.
    
    Fix:
    Added NV_CTRL_ATTR_NVML_GPU_GRID_LICENSABLE_FEATURES attribute to get feature code
    of the currently licensed feature.
    Used the existing NVML api nvmlDeviceGetGridLicensableFeatures to fetch this feature code.
    And then query this licensed feature code in nvidia-settings.
    Setting the restart required status message when there is mismatch in
    the queried licensed feature type and the feature type read from gridd.conf/UI.
    
    Testing done:
    Verified on NMOS, correct license status message is displayed.
