SystemUI: Fix for fix ActiveDisplay (Emergency)

this an emergency fix for last patch was merger
using another logic to determine, when need to hide Statusbar and
Navigationbar
we dont want systemui visibility reset if lockscreen still enable and
ActiveDisplay force to Turn Off
Correct ActiveDisplay visibility when launch Ongoing Notifications
fix Back button navbar cant work on some conditions
since AD detect User Activity, we dont want to override UserActivity
inside View, so do only if AD visibilty are Gone
also add patch to keyguard, do not reset if ActiveDisplay visibility
Visible
