Improve UX of Wi-Fi QR code scanner enrollee flow

Browse Source 
1. Do not start WifiSettings after enrollee success
2. Return WifiConfiguration to the calling object after enrollee success
3. In WifiDialog, do not show scan button if Save button is not visible to users
4. Fix scanner button may not respond problem by setting listener for scanner
   button of ssid field and password field
5. If SSID is assigned, only allow to enrollee for the network of assigned SSID
