ash: Open app list and highlight the installed app.

- Add a NOTIFICATION_APP_INSTALLED_TO_APPLIST similar to
  NOTIFICATION_APP_INSTALLED_TO_NTP;
- OpenAppInstalledNTP -> OpenAppInstalledUI, which opens applist on ash and
  fires NOTIFICATION_APP_INSTALLED_TO_APPLIST;
- Make AppListModelBuilder observes extension loading/unloading and
  NOTIFICATION_APP_INSTALLED_TO_APPLIST and updates model accordingly;
- Make AppListView SetModel on its delegate explicitly;
- Make AppListViewDelegate hosts a builder as its member and pass the model
  used by app list to the builder;

BUG=117087
TEST=Install an app and app list should open and highlight the installed app.
