For Matter, a device may have a single host with multiple A/AAAA
records, but multiple PTR/SRV pairs that represent different
operational identities for the same device.
Currently, MdnsResponseDecoder looks for only a single matching
MdnsResponse by hostname when looping through the A/AAAA records
(which will leave the second response incomplete). Updated with a
flag that will allow returning all MdnsResponses which match the
given hostname and update the Inet records for all responses.
Bug: 254155029
Test: atest FrameworksNetTests
Verified with a Matter device with two identities that the
second response is incomplete without this change.
Additionally, added unit tests to verify the before and
after behavior with a real packet capture from the device.
