[RONs] Setup AOD Skeleton View when added

AOD Skeleton View remains visible on the screen since view is initialized sometime after VM state is bound. This CL sets the last View State for AOD Skeleton View visibility when it is added to View Tree.

Fixes: 419762883
Flag: android.app.ui_rich_ongoing
Test: Post a RON when AOD is not enabled. Check the lockscreen. Check before/after Screenshots
