Use a dns connection filter to resolve hostnames where their addresses are locally resolved and forwarded to the SOCKS proxy. This makes all improvements, like in #21295 for example, also apply to socks connections. Curl_resolv() is now only called from a DNS filter. (ftp still calls Curl_resolv_blocking() in two places, one of which may be replaceable with a DNS filter as well to remove the block, tbd) Closes #21297
