Add SkipNativeNetworkCreation flag in NetworkAgentConfig
This flag allows ConnectivityService to skip native network creation,
deferring this responsibility to Tethering. This is necessary because:

- ConnectivityService requires the NetworkAgent to be in the CONNECTED
  state to configure routing and invokes NetworkCallback#onAvailable
  once ready.
- Tethering requires lower-layer interactions to be completed before
  notifying applications.

This approach ensures proper synchronization between ConnectivityService
and Tethering during network setup.

Long-term, all netd operations should be handled by ConnectivityService
when it supports early native network creation in the CONNECTING state.

As a mid-term solution, this flag enables Tethering to manage native
network creation within the IpServer.

Support NetworkStats#addEntries API
Currently, NetworkStats#addEntry creates a new instance
containing the requested result instead of mutating the
original object. This creates a heavy memory footprint
when the caller invokes it in a loop because a new NetworkStats
instance is created whenever an addEntry is called.

This change introduces a new API that allows callers to
add a set of entries to a NetworkStats instance. This new
API will clone the instance only once, return the newly
created (and modified) instance, and ensure that the original
instance remains immutable.

Additionally, the change adopts config libraries for flagging
the API and corresponding CTS tests, since Android U-based
branches are no longer downstream of current development branches.

which is annotated with @UnsupportedAppUsage. NetworkTemplate

Simplify per-target-SDK LinkProperties tests.
Currently these tests run as hostside tests and require a lot of
boilerplate, including their own CtsHostsideNetworkTestsApp3
build target.

Move the coverage to LinkPropertiesTest using the new-ish
@CtsNetTestCasesMaxTargetSdk31 annotation, and remove the
hostside tests.

The only test that is not being moved is one that checks the
behaviour of disabling the compat change on T. This test is not
very useful because it can only run on userdebug builds and not
on production builds, because CtsHostsideNetworkTestsApp3 targets
SDK 33. We do have test coverage for disabling the compat change
on an app targeting SDK 31, where it is allowed.

Let LinkProperties#getRoutes() keeps returning all routes before T
Starting from T, VpnService supports exclude routes, which will
make the caller to get both of include routes and exclude routes
from LinkProperties#getRoutes(), and it's not expected to get the
exclude routes before T in production code even though the code
returns all routes.

But there is a CTS - LinkPropertiesTest#testRouteAddWithSameKey()
will try to add an exclude route and check if the result of
LinkProperties#getRoutes() contains that exclude route or not.
And the test is failed now since LinkProperties#getRoutes() will
only return include route if compat feature - EXCLUDED_ROUTES is
disabled. (EXCLUDED_ROUTES is enabled starting from target SDK T)

To fix this test failure, let LinkProperties#getRoutes() keeps
returning all routes if SDK is before T. This avoids changing
behavior on S, and even though there is still a behavior change
when upgrading to T, apps are unlikely to be relying on such
behavior, especially outside of tests.

Bug: 238061814
Test: Run "atest CtsNetTestCases:LinkPropertiesTest" on S build
      with mainline module which contains this patch.

Fix LinkProperties exclude routes tests on user builds.
The tests fail on user builds because they target T and attempt
to override the compat change, which is not allowed on user
builds because the change defaults to on for apps targeting T+.
Fix this by marking the tests max target SDK 31.

Also improve the tests a bit:

- Use a RuleChain to make it explicit that
  CtsNetTestCasesMaxTargetSdk31 should be evaluated before
  EnableCompatChanges (otherwise the compat change rule would
  crash on user builds even if the max target SDK rule was going
  to skip the test anyway).

- Fix the IgnoreUpTo for all exclude route tests to say S+.
  Currently:
  - One says R+, which is incorrect because the updated
    LinkProperties code is in the connectivity module, which only
    goes back to S, not R.
  - The others say T+, which is incorrect because the update code
    is present on S.

Fix: 233553525
Test: LinkProperties test in CtsNetTestCasesLatestSdk passes on T user build
Test: LinkProperties test in CtsNetTestCasesMaxTargetSdk31 passes on T user build
