Modernize deprecated getConnectionInfo() in WifiInfo

[HollowMan6]

WifiInfo.getConnectionInfo() was deprecated in API level 31. Starting with Build.VERSION_CODES#S, WifiInfo retrieval is moved to ConnectivityManager API surface. WifiInfo is attached in NetworkCapabilities#getTransportInfo() which is available via callback in NetworkCallback#onCapabilitiesChanged(Network, NetworkCapabilities) or on-demand from ConnectivityManager#getNetworkCapabilities(Network).

WifiInfo.calculateSignalLevel(int, int) was replaced in 2a63e28

It may not be a good time to replace WifiInfo.getConnectionInfo() since we need to use callback for that. If we use the synced getNetworkCapabilities (Network network), it will remove any location sensitive data in the returned NetworkCapabilities (the SSID). Some TransportInfo instances like WifiInfo contain location sensitive information. To retrieve this location sensitive information (subject to the caller's location permissions), use a NetworkCallback with the NetworkCallback#FLAG_INCLUDE_LOCATION_INFO flag instead. This method returns null if the network is unknown or if the |network| argument is null.
