Fix API in CaptivePortal and ConnectivityManager
- Remove CaptivePortal constructor from SystemApi. This constructor was
added in Q timeframe and ends up being unnecessary since
CaptivePortal creation was refactored to ConnectivityService because
of visibility issues on ICaptivePortal.
- Rename getAvoidBadWifi to shouldAvoidBadWifi
- Add permission annotation for shouldAvoidBadWifi
Test: flashed, WiFi and captive portal works
