NFC settings cleanup.
Remove NFC settings from Settings.System. The NFC Service tracks them
internally using SharedPreference.
Revert back to enable()/disable()/isEnabled() - Tag discovery is the
only functionality NFC service performs right now so we don't need to
break it up more explicitly yet. enable/disable is the global NFC
on/off and later we'll add enableDiscovery(), enableTagEmulation(),
enableSecureElement() etc as needed.
