[BR06] Support check whether network is blocked by data saver

This change adds a DataSaverStatusTracker, which is a helper
class to continuously track data saver status through NPMS
public API and intents. ConnectivityManager#isUidNetworkingBlocked
would use this cached information along with bpf maps to decide
whether networking of an uid is blocked.
