Non-functional simplification of NetworkChangeNotifierAutoDetect code

Turns out NetworkState was only needed for the current default network,
so simplify unnecessary pieces.  This is in preparation for adding
WiFi SSID to NetworkState, so I wanted to reduce the dependence on
NetworkState so the code wouldn't be required to fetch the Wifi
SSID as much.

Remove WiFi link speed tracking from Android NetworkChangeNotifier

Chrome has eschewed ACCESS_WIFI_STATE permission so this code is
disabled.  Chrome is also the only user of this NetworkChangeNotifier
signal so remove the code as it is consequently dead.

Non-functional improvement to reduce querying of WiFi SSID upon startup

Include WiFi SSID in NetworkState so it can be reused without re-querying.
Also improve how we fetch WiFi SSID if needed:
1. On Android 4.2+ devices, SSID can be retreived from NetworkInfo which
   NetworkChangeNotifierAutoDetect already queried
2. When an app has the ACCESS_WIFI_STATE permission, the SSID can be
   queried quickly directly from WifiManager.

Non-functional optimization to Android NetworkChangeNotifier startup

Ignore the initial onReceive() callback when registering a
BroadcastRecevier for a sticky Intent as it doesn't offer any
new information.

Non-functional optimization to Android NetworkChangeNotifier startup part 2

Avoid needlessly computing whether a change signal needs to be sent out during
initialization (when there can't be a change).  This allows avoiding
needlessly requerying the current connection state.
