Show default app icon in default app screen.

- Renamed AdvancedAppSettings to DefaultAppSettings.
- Add logic to DefaultAppPreferenceController to also display icon.
- Modified DefautlAssistPrefController to suppress gear icon, and use
  the controller in default app setting UI to display icon.
- Remove dynamic injected payment setting activity and create the
  setting statically in xml.
- Add DefaultPaymentSettingsPreference to display default payment app
  title (no icon because we can't get it)
