socks: support CURLAUTH_ONLY in CURLOPT_SOCKS5_AUTH

The SOCKS5 method negotiation always offered "no authentication" and
accepted it, so the bitmask could not express that the connection has to
be authenticated. CURLAUTH_NONE is zero and cannot say it either.

With CURLAUTH_ONLY set, the method is neither offered nor accepted, and
a connection that did not authenticate is not reused.

Document both, and add tests 1742, 1743 and 1744.

Closes #23003
