Get ApnIpType from ConnectivityManager#getLinkProperties()
As Telephony hidden API ServiceState#getDataRoamingFromRegistration() is not available for GNSS in S, get ApnIpType from ConnectivityManager#getLinkProperties(). Test: Emergency NI SUPL test with/without SIM, SI SUPL test in FI roaming and domestic network. Bug: 152891065 Change-Id: I19e0e531a57af32ad82377480e8a3a2fa5532e93
