Nick Khyl f23932bd98 net/dns/resolver: log forwarded query details when TS_DEBUG_DNS_FORWARD_SEND is enabled 
Troubleshooting DNS resolution issues often requires additional information.
This PR expands the effect of the TS_DEBUG_DNS_FORWARD_SEND envknob to forwarder.forwardWithDestChan,
and includes the request type, domain name length, and the first 3 bytes of the domain's SHA-256 hash in the output.

Fixes #13070
