[Search][Motion] Normal<->AllApps transition revamp

Preview video attached to BR

Key changes:

- SearchUiManager#getScrollRangeDelta is removed. AllApps initial vertical offset is now controlled by deviceProfile.allAppsOpenVerticalTranslate.
- ShelfScrimView is renamed to AllAppsScrimView. Scrim no longer does vertical translate with AllApps open.  Shelf/overview related code removed.
- Scrim and AllApps content transition are animated with different interpolators. Scrim color is a blend of accentColor and allAppsScrim with proportion determined by progress*TINT_DECAY_MULTIPLIER
