Change the use of ScreenLifecycle to WakefulnessLifecycle.

This is a better fit for the signal in launcher, since it identifies
whether the device is awake or asleep, where asleep also inclues AoD.

Also adding SYSUI_STATE_NOTIFICATION_PANEL_VISIBLE to the IntDef and
debug getSystemUiStateString, since it was missing.

Test: manual, unit tests
