Filter out unsupported security type for DPP configuration.

Browse Source 
There is different Wi-Fi security support between ZXing's Wi-Fi QR code
format and Wi-Fi DPP QR code format.

  ZXing's Wi-Fi QR code format: supports WEP / WPA / none security
  Wi-Fi DPP: supports WPA / SAE

So we will have different UI behavior for different security.

  WEP & none security: only support QR code generator
  WPA: supports both QR code generator & scanner
  SAE: only supports QR code scanner
  others: don't support. The share button is invisible

Test: manual test
