conradchen 698cf9b45e [AppBarLayout] Save and restore scroll state during scroll range recalculation ...

When scroll range changes, the current scroll position may not make sense anymore. Therefore we need to save the scroll state and restore it after the scroll range is invalidated. This change reuses and refactors the existing saving instance state logic to support this need. Also adds a flag to denote "fully expanded" state to avoid improper scroll position calculation when views are still being initialized.
