3. Set android:contentDescription for Wi-Fi enrollee scan button

   WifiDppQrCodeScannerFragment
5. Auto trigger Talkback to speak title & summary in WifiDppAddDeviceFragment &
   WifiDppChooseSavedWifiNetworkFragment
6. Auto trigger Talkback to speak summary change in WifiDppAddDeviceFragment
7. Auto trigger Talkback to speak error message in WifiDppQrCodeScannerFragment
