[BUG] Matter hubs that use minimal mDNS will often excessively query devices to fetch AAAA records, leading to poor 2.4 GHz performance in extreme cases

[ndyck14]

Reproduction steps

I have 8 matter wifi devices and a variety of matter thread devices.

I see frequent queries to a variety of different host names. I've been able to link these spurts of packet queries to equivalently timed prints that originate in the SDK:

connectedhomeip/src/lib/dnssd/Resolver_ImplMinimalMdns.cpp

Line 204 in 0180ee6

ChipLogDetail(Discovery, "SRV record already actively processed.");
