docs: make each libcurl man specify protocol(s)

The mandatory header now has a mandatory list of protocols for which the
manpage is relevant.

Most man pages already has a "PROTOCOLS" section, but this introduces a
stricter way to specify the relevant protocols.

cd2nroff verifies that at least one protocol is mentioned (which can be
`*`).

This information is not used just yet, but A) the PROTOCOLS section can
now instead get generated and get a unified wording across all manpages
and B) this allows us to more reliably filter/search for protocol
specific manpages/options.

Closes #13166

    res = curl_easy_perform(curl);
    if(CURLE_OK == res) {
      res = curl_easy_getinfo(curl, CURLINFO_NAMELOOKUP_TIME, &namelookup);
      if(CURLE_OK == res) {
        printf("Time: %.1f", namelookup);
