1. set fragment icon for WifiDppChooseSavedWifiNetworkFragment
2. set fragment icon of success for WifiDppAddDeviceFragment
All Wi-Fi DPP fragment icons are VectorDrawable of instinct size
24dp draw on a 48dp canvas. Except for ic_devices_check_circle_green,
it's a LayerDrawable of different size. I dynamically change ImageView
layout width & height between these 2 different kind of drawable.

1. WifiDppQrCodeBaseFragment only declairs common UI components between fragments.
2. Initiate UI components in onViewCreated of each View.
3. Remove the only one usage of @NonNull since it should be used consistently
throughout the class if we want to use it.
4. Use android.R.id for icon/title/summary
