kiosk: Network connectivity test during launch.
- Add NetworkStateInformer and ErrorScreenActor to
AppLaunchSplashScreenHandler;
- AppLaunchSplashScreenHandler sends network state
to its delegate (AppLaunchController) during network
check;
- AppLaunchController decides when to show network
configure UI and call AppLaunchSplashScreenActor
to show it (via ErrorScreenActor);
- Show network config UI for enterprise kiosk;
- Add a 'Reboot' button for kiosk network error;
- Add a PromptForNetworkWhenOffline boolean field to
DeviceLocalAccountsProto to control whether to show
network config UI for enterprise managed kiosk;
