Added systemui controller to control system bars. 

When config_remoteInsetsControllerControlsSystemBars is true,
DisplaySystemBarsController provides its own policy of how system
bars are displayed for specific packages. Currently limited to
only auto versions of Android.

         In the Automotive case, this is helpful if there's a requirement for an UI element to be on

         screen at all times. Setting this to true also gives System UI the ability to override the

         visibility controls for the system through the usage of the

         "SYSTEM_BAR_VISIBILITY_OVERRIDE" setting.

         Ex: Only setting the config to true will force show system bars for the entire system.

         Ex: Setting the config to true and the "SYSTEM_BAR_VISIBILITY_OVERRIDE" setting to
