Cleanup remnants of dynamic_system feature flag.
This piece of code only makes sense when we had the feature flag.
Now that the feature flag is deprecated, we shouldn't check the
DynamicSystemManager.isInUse() anymore, because we actually do want to
post a notification when DSU is installed but not in use.

Bug: 176795908
Test: Install a DSU, reboot into guest system, reboot back to host
  system, verify the BootCompletedReceiver is active.

The API surface of com.android.dynsystem is already protected by
privileged permission android.permission.INSTALL_DYNAMIC_SYSTEM,
which is only granted to system apps or priv apps.
Thus the feature flag check here is redundant, because eligible
callers of this API (system app) can also set the feature flag.

Netd currently calls maybeCloseSockets before adding/removing users for
network. The task should be moved from netd to CS. In this way, we can
handle WiFi lingering more easily in the future.

IIpConnectivityMetrics is gaining two new methods. Update the
subclass of that class used in NetworkWatchlistServiceTests to
reflect the new methods.

Test: m FrameworksServicesTests
Change-Id: I3eb82680b6b3dd6b457095a484cf55560ff1088b

Currently, ConnectivityService calls the IpConnectivityMetrics
service class directly to log default network events. This is
incompatible with ConnectivityService being in a mainline module.
Replace direct access to IIpConnectivityMetrics with public
methods in IpConnectivityLog, which is @SystemApi class.

The new methods are not yet @SystemApi, but they can be made so
if desired. Alternatively, these metrics could be deleted.

Also remove the IpConectivityMetrics service from the
service-connectivity JAR, and go back to starting it from
SystemServer.java, which is what was happening a few hours ago
before aosp/1542626 was merged.

Adds Restricted Mode functionality to NetworkPolicyManager. When this
mode is turned on (via setting), only apps with
android.permission.CONNECTIVITY_USE_RESTRICTED_NETWORKS will be able to
use the network. For all other apps, the network will be blocked by the
firewall. This is controlled by a new allowlist firewall chain
fw_restricted_mode.

As a first step, this implementation still requires a reboot after the
enabling / disabling the mode to take effect. I will provide the dynamic
configuration in the next CL.

This gives more flexibility to the user (e.g. will allow restricted
networking mode to update all firewall rules at once) and removes some
unnecessary code.

Connectivity service is going to become a mainline module which
will not able to access hidden APIs. NetworkPolicyManagerInternal
is a internal serivce that CS can't be access after be a mainline
module. Thus, replace NPMI#isUidNetworkingBlocked() to similar
method NPMS#isUidNetworkingBlocked() and create new API
NPM#isUidNetworkingBlocked() to support CS usage.
