[Offline pages] Reinstating the offline icon on tablet and fixing verbose state/URL emphasis

This patch addresses the following problems:
* Offline icon is not shown in omnibox on tablets
* Offline verbose status is sometimes shown with green padlock
* URL emphasis lags behind security icon update.

This fix does the following:
* Moves the offline icon from the navigation button to security button
* Ensures that navigation button is never shown on phones
* Calculates when to show: navigation/security/no button, to properly
  show or hide icon container.
* Moves verbose status visibility control to security button related
  code (as that is where we show offline stuff and would show verbose
  security states)
