[mdns] separate the multicast reply quota for IPv4 and IPv6

This CL separates the multicast reply quota for IPv4 and IPv6. Before
this change, when an IPv4 mDNS query and an IPv6 mdns query arrives at
the same time for the same record (which is a common behavior for DNS-SD
resolvers), MdnsRecordRepository will only respond to one of them. The
other response will be throttled silently.

It's especially problematic when the IPv4 query and IPv6 query are sent
by different hosts. One of the hosts will get no reply.

Bug: 335096961
Test: Unit test and verified on a local device.
