Create version 2 of InstalledAppDetails

- this is the first step for converting InstalledAppDetails into
DashboardFragment
- add a feature flag to determine whether to show the new installed app
detail page.
- decouple the fragment from AppInfoBase: extends from
SettingsPreferenceFragment directly and copy all codes from
AppInfoBase.
