Expand wfcSpnFormats with more options, in order to support
requirements from more operators.
Five new options are added in this patch. The list of available options
becomes:
0: %s
1: %s Wi-Fi Calling
2: WLAN Call (New)
3: %s WLAN Call (New)
4: %s Wi-Fi (New)
5: WiFi Calling | %s (New)
6: %s VoWifi (New)
strings.xml in values-mcc302-mnc370 and values-mcc302-mnc720 was deleted.
The same requirement can now be achieved by configuring KEY_WFC_SPN_FORMAT_IDX_INT
or KEY_WFC_DATA_SPN_FORMAT_IDX_INT to 4.
