[Dynamic Home] Make a new page for all top level settings

Since we are moving conditionals/suggestions to a different place, there
is no need to use DashboardSummary to display top level settings any
more. We can simplify a lot of code for top level settings and reduce it
to a standard DashboardFragment.

- Create a new DashboardFragment + xml for all top level internal items
- Add a PreferenceController to provide summary for Network & internet
  item.
- Mark a bunch of things deprecated for future work.
