Update UI to use a smaller icon for ManageApplication page.

- Rewrite preference_app.xml to have a small icon
- Update ApplicationViewHolder to hide/show summary row dynamically
  - but only do this for notification settings - this UI has empty
    summary for most row. For other UI, just keep the empty summary row
    until summary comes in. If we also hide/show summary row there will
    be a height change animation which is janky.
