This patch adds MAC address support for EthernetNetworkSpecifier under
@hide flag.
After adding the support, EthernetNetworkSpecifier will be able to be
matched by MAC address in addition to existing interface name match. The
specifier can be satisfied with either MAC address and/or interface
name.

Avoid duplicate calls to getValues for non-matched entries. Performance
experiments suggest it is worth the cost of the additional BitSet
allocation to keep track of what matched. BitSet performs slightly
better, and allocates/uses/frees less memory, than a boolean array.

Skip including the subtype PTR query for both announcement and offload
packets. This is necessary because devices like Googlecast have
numerous subtypes. Including these subtypes in the packets can easily
exceed the MTU limit. Furthermore, the Wi-Fi firmware has limited RAM
available for hardware offload, and including subtypes would consume
excessive memory resources needed for the offload code.

The NsdManager.registerService() method was originally scheduled to
become a public API in the 25Q2 release. However, this transition did
not occur as planned. The current target for making this method a public
API is the 25Q4 release. In the interim, the @UnsupportedAppUsage
annotation is being added. This is necessary to support an internal
MediaShell use case for the 25Q2 TV release. This change marks the API
as available in the dex so callers can call without being blocked by
hidden API restrictions. This API will be marked as public API
immediately after this change for 25Q4.

This change introduces client-side rate limiting for TrafficStats
APIs to address a performance issue caused by excessive calls,
resulting in high CPU usage and binder contention. By caching
traffic statistics on the client side, we reduce the frequency
of calls to NetworkStatsService, improving overall system
performance and mitigating potential privacy concerns related
to traffic analysis fingerprints.
This client-side caching mechanism will be disabled and gradually
enabled through a feature flag rollout.

This is a no-op change since the config is not used yet, and
the feature flag will be gradually rolled out instead of enabled
by default.
However, this change is necessary for follow-up changes to enable
toggling the feature and configuring its behavior through device
configuration flags.
This change includes:
1. Disable the service-side cache flag if the client-side flag
is enabled.
2. Since the apps don't have enough permission to check the
feature flag from DeviceConfig. Provides a binder interface
for returning per-UID config,
which only returns cache enabled if the SDK level is V+
or the app's target SDK is V+.

Follow-up from aosp/3249945. If the system caller queries stats
for other UIDs, the caller would get UNSUPPORTED.
This follows the official documentation, where the API would
not return stats for all other UIDs.
However, partners or other legacy callers might already depend
on this undocumented behavior. Changing this behavior might
damage existing apps.
Thus, this change reverts the behavior change introduced at
aosp/3249945 and allows a system caller to query stats for
other UIDs.

This change includes:

2. Use a dedicated class to pass the result of
get{Total|Iface|Uid}Stats, as it is 25% faster than passing
a NetworkStats object through the binder interface.
3. Remove the binder interface only used by the test.
4. Remove NetworkStatsBinderTest on R and S, since the binder
interface is removed, the mainlined service does not run on
those versions and the chance of breaking these tests on
R and S is low.
5. Remove useless TODO comments.

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.

If the IpSecTransform is being manipulated in
multiple threads, there is a race between the
clearing of the resource id (setting it to
INVALID_RESOURCE_ID and making binder calls
with it. This wasn't a significant problem before
becasue the only side effect was that it could
occasionally cause an IAE instead of an ISE when
the caller was doing something weird. Unfortunately
the exception type now matters because it is being
relied upon to provide a callback rather than a
throw in the event of an error. Accordingly reads of
mResourceId have to be synchronized against the
the possibility of close() of that resourceId to
ensure that the right exception is thrown on the
service side of the binder.

This change put a rate-limit on TrafficStats getter APIs to
reduce the need of accessing bpf map. For any caller who calls
this method within 1 second, a stale result will be returned.
One expected outcome is this change would break any test which
relies on immediate change of the result of TrafficStats after
making network traffic. Thus, related tests are fixed in the
counter part CL accordingly.
