[net/dns] Add per-address-family histograms AsyncDNS.ResolveSuccess_FAMILY_* and per-qtype histograms AsyncDNS.TransactionSuccess_*.
Currently observed AsyncDNS.ResolveSuccess (duration of DnsTask) is almost twice as long as AsyncDNS.TransactionSuccess (duration of DnsTransaction). This could be attributed to dual-stack resolutions which involve two DnsTransactions, but at the same time the difference between DNS.ResolveSuccess_FAMILY_IPV4 and ..._UNSPEC (duration of ProcTask) is much less pronounced suggesting that SystemDNS resolves names on dual-stack hosts differently than AsyncDNS.
This measurement will allow us to determine how much of the observed overhead of DnsTask over DnsTransaction can be attributed to dual-stack lookups.
