Merge deep shortcuts in rounded rect

- DeepShortcutViews are added to ShortcutsItemView, which
  is in PopupContainerWithArrow
- Moved some shortcut-specific logic to ShortcutsItemView
  (namely, touch/long-click handling for draggin shortcuts)
- Moved round-rect clipping to PopupItemView
- Removed collapseToIcon() logic, including
  PillWidthRevealOutlineProvider, which was only used for
  that purpose. It isn't necessary now that the deep
  shortcuts have no background themselves.
- Replaced focus pill drawable with ripple effect on
  shortcuts and notification view.
