based on curl#16100 Add a 'wanted' major HTTP version bitmask next to the 'allowed' bitmask in HTTP version negotiation. This will try connections as specified in 'wanted', but enabled Alt-Svc and HTTPS-RR to redirect to other major HTTP versions, if those are 'allowed'. Changes libcurl internal default to `CURL_HTTP_VERSION_NONE` and removes the code in curl that sets `CURL_HTTP_VERSION_2TLS` if the command line does not say anything else.
