Fix touch handling for glanceable hub over dream

When dreaming, the glanceable hub can be opened on top and touch input
should go to the hub.

This change uses the hub's transition state to force
NotificationShadeWindowView to be visible instead of the
ForcePluginOpen APIs, which seem to affect touch handling.
