New connection filter `cf-dns` that manages DNS queries. If hands out addresses and HTTPS-RR records to anyone interested. Used by HTTPS and IP happy eyeballing. Information may become available *before* the libcurl "dns entry" is complete, e.g. all queries have been answered. The cf-ip-happy filter uses this information to start connection attempts as soon as the first address is available. The multi MSTATE_RESOLVING was removed. A new connection always goes to MSTATE_CONNECTING. The connectdata bit `dns_resolved` indicates when DNS information is complete. This is used for error reporting and starting the progress meter. Removed dns entries `data->state.dns[i]`, as the `cf-dns` filter now keeps the reference now. Many minor tweaks for making this work and pass address information around safely. Closes #21027
