Disable Wi-Fi calling roaming preferrence while using NTN.

When phone is connected to non-terrestrial network, carrier can specify
whether to override Wi-Fi calling roaming mode or not using
KEY_OVERRIDE_WFC_ROAMING_MODE_WHILE_USING_NTN_BOOL.

If KEY_USE_WFC_HOME_NETWORK_MODE_IN_ROAMING_NETWORK_BOOL is false,
and if KEY_NTN_EDITABLE_WFC_ROAMING_MODE_BOOL is true and
if KEY_OVERRIDE_WFC_ROAMING_MODE_WHILE_USING_NTN_BOOL is true, then
Wi-Fi calling roaming preferrence is disabled.
