Glitchy notifs on clock size change
Notifications weren't animating Y position changes as expected. In order to synchronize the animation, we tether the intrablueprint transition state into KeyguardRootViewBinder which listens for placeholder position changes and forwards them to the notification code. This function now skips certain layouts during transitions to prevent later layout changes from conflicting with the running animation. These layouts are erronous to the transition and suppressed by the transition directly for other relevant lockscreen elements. To facilitate two binders relying on the same transition state, I've moved the transition management logic from the binder to the model, but otherwise not modified it much. This makes the state available to more components, allows the binder to be stateless, and lets us convert it to being a top-level kotlin object like other binders. I've also corrected an issue where the notif shelf would animate in when the clock size changed. AodNotificationIconsSection.applyConstraints was not setting the visibility, so it'd default to VISIBLE for a moment when it was applied. The transition would pick up this incorrect transient visibility value and animate the element in.
