Change print setting from a dynamic tile to static pref

...because dynamic tile is a lot harder to index correctly.

- Removed metadata that makes PrintSettings a dynamic tile.
- Added PrintSettings into connected_device xml.
- Added a new PreferenceController - all summary updating logic is
  copied from PrintSettingsFragment
