Use swipe helper for swiping

* Use SwipeHelper for swiping, in SwipeableListView for regular favorites.
  SwipeHelper and SwipeableListView are copied from DeskClock, with minor
  modifications (to prevent swiping or call log items, and all contact buttons).
* Make ContactTileRow implement SwipeHelperCallback so that tiled favorites
  can be swiped.
* Remove PhoneFavoriteGestureListener
* Add selectable item backgrounds to undo buttons on removal dialog
* Moved common code shared by PhoneFavoriteRegularRowView and
  PhoneFavoriteSquareTileView to PhoneFavoriteTileView
* Standardize layout ids for phone_favorite_regular_row_view and phone_favorite_tile_view
* Add long click listener to PhoneFavoriteTileView to trigger the start of a drag
  and drop operation
* Remove any contact entries that are in the removal dialog phase if the app is paused
