Add possibility to configure SPN during Wi-Fi Calling and Flight mode

Adds carrier config setting KEY_WFC_FLIGHT_MODE_SPN_FORMAT_IDX_INT
which controls the spn text when flight mode is enabled and
Wi-Fi Calling is registred.

Expands wfcSpnFormats with more options, in order to add suitable
options without %s during flight mode.

Four new options are added in this patch. The list of available options
becomes:
0: %s
1: %s Wi-Fi Calling
2: WLAN Call>
3: %s WLAN Call
4: %s Wi-Fi
5: WiFi Calling | %s
6: %s VoWifi
7: Wi-Fi Calling (New)
8: Wi-Fi (New)
9: WiFi Calling (New)
10: VoWifi (New)
