Following CL adds idleTimer for multiple networks and track activities
including non default network on V+
Current LegacyNetworkActivityTracker uses transport type as an idleTimer
label but this makes it difficult to have multiple idleTimers.
So, this CL updates LegacyNetworkActivityTracker to support using netId
as an idleTimer label.

A new firewall chain is needed to configure background network
restrictions for apps.
This change only adds the API stubs and traffic controller constants to
make the chain work. Policy changes using this chain will follow in
the framework code.

BpfNetMaps uses java library for updating bpf map as the default code
path.
This is already released to 100% production without any issues.
So this CL removes the old code path from BpfNetMaps.
Note that native_init only opens the bpf maps if sEnableJavaBpfMap is
true.
But if sEnableJavaBpfMap is true, no native code in TrafficController
access the bpf map.
So this CL can remove native_init.
Following CL will remove the nativce codes for old code path.

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.

This is needed for data stall detection mechanism in NetworkStack
to get the information about whether the network is blocked for
a given uid and conditions. Because the API will be called
frequently from NetworkStack to resolve all status for all uids
on the device, the API cannot call into the service which
creates IPC. Instead, the API need to directly access bpf maps
in the user process to retrieve the status. In this case the
user process is the network stack, the access control is provided
by linux file permission and selinux.

In particular, this fixes a bug where a non-validated destroyed

1. At present, the transportTypes in NetworkCapabilities have been
passed into DnsManager::updateTransportsForNetwork() as a parameter. In
the following CL, we also need to pass the 'metered' (also in
NetworkCapabilities) as a parameter to the function. Instead of passing
the members of NetworkCapabilities one by one, it is better to pass the
entire NetworkCapabilities.
2. Rename updateTransportsForNetwork() to
updateCapabilitiesForNetwork().
