Add occlusion logic to OverlayViewGlobalStateController and CarKeyguardViewController

Activity has a public API setShowWhenLocked, which, if set to true,
allows it to be shown when the device is locked, thereby "occluding"
the Keyguard.

In the Phone OS implementation, when an occluding Activity is showing,
Keyguard is temporarily dismissed and StatusBar expands.

In the AAOS implementation where SystemUI components are mounted to
the SystemUIOverlayWindow, OverlayViewGlobalStateController hides all
views mounted to it unless they are configured to be shown even during
occlusion.
