Swipe to dismiss suggestions

- Move dismiss suggestion logic into feature provider
- In DashboardData, use hashcode as suggestion's stable id. This is much
  more likely to provide a truely stable id for each suggestion card.
  Eventually I want to use hash for all tiles to provide stable id.
- Add a SuggestionDismissionController to handle swipe to dismiss
  callbacks
