- Layout of notif shade is no longer custom, so need to handle
insetsIgnoringVisibility on client.
- Do not special case Keyguard anymore. Just treat it as regular
control target.
- No more special sauce to hide navigation bar on Keyguard.
- Treat it as BEHAVIOR_SHOW_TRANSIENT_BARS_ON_SWIPE but don't
actually do that in DisplayPolicy
