Zhang Boyang 53dd0d7809 net: make go resolver aware of network parameter
Currently, the go resolver always send two DNS queries (A and AAAA) even
if tcp4/udp4/ip4 or tcp6/udp6/ip6 is used. This can cause unwanted
latencies when making IPv4-only or IPv6-only connections.

This change make go resolver aware of network parameter. Now, only one A
query is sent when tcp4/udp4/ip4 is used, and vice versa for
tcp6/udp6/ip6.

Fixes #45024
