Use NetworkCallback to determine active data sub

- SubscriptionManager#getActiveDataSubscriptionId() does not return
the current active data subscription immediately; it takes about 30s
to update its cache.
- Moreover when internet is on WiFi, this API returns the default
data subscription, instead of INVALID_SUB_ID.
- IWLAN aligns with QNS on using the ConnectivityManager.NetworkCallback
to determine the actie data sub from NetworkCapabilities.
