Existing MdnsRecordRepositiry#getReply will send a NSEC RR in the reply
when 1) a query for a unique RR is not found or 2) any unique name which is
included in the answer sections. The second one is not aligned with the
spec:
```
On receipt of a question for a particular name, rrtype, and rrclass,
for which a responder does have one or more unique answers, the
responder MAY also include an NSEC record in the Additional Record
Section indicating the nonexistence of other rrtypes for that name
and rrclass.
```
This commit fixes the issue in 2) by checking that all unique records of
the name are included in the answers before adding a NSEC record.

FastDataInput for reading persistent data is currently disabled
by default. This functionality will be gradually enabled through
A/B experiments to assess its impact.
One-shot boot time increase up to 10 second is one expected
outcome in worst case. Currently, the persistent data was loaded
when the first caller query it, but in this change it will be
done twice in the boot stage due to the needs of doing comparison.

This commit optimizes the mechanism to examine the TCP sockets
based on the VPN UID range.
The automaticOnOffKeepalives will be paused/resumed by checking
the TCP sockets status on the VPN network. The existing design
considers all UIDs, not the UID ranges for the specific VPN
network. This may lead to an inaccurate judgement to not to
stop the keepalive even when there is no socket on the VPN
network.
This commit is also a part of follow-up work from aosp/2354202
to use structized class to parse the TCP sockets.

This commit builds upon CL aosp/2817455 by adding a new NsdManager API to
update registered services directly, eliminating the need for exit and
re-announcement messages. This preserves compatibility with existing
apps without requiring an API bump. If an app registers a service with
the same listener and NsdServiceInfo, it's treated as an update request.

Currently, the MdnsReplySender doesn't have a dedicated test
class to verify its functionality. To address this gap, add the
MdnsReplySenderTest class, which can test all methods within the
MdnsReplySender class.

Existing MdnsRecordRepositiry#getReply will result in duplicated RRs in
answer and additional records sections if multiple PTR questions for the
same service are received in a single query message.
This commit fixes this by using a Set<> for maintaining the RR set and
moving the NSEC construction to outer of the addReplyFromService() after
all answer and additional records have been added.
This commit also refactors the unit tests to cover more cases of
multiple queries other than PTR records
