Add support for the RFC7250 certificate-type extensions. Alows the use of only private keys for connection (i.e. certs not needed). Add APIs Add unit tests Add documentation Add s_client/s_server support Reviewed-by: Matt Caswell <matt@openssl.org> Reviewed-by: Viktor Dukhovni <viktor@openssl.org> (Merged from https://github.com/openssl/openssl/pull/18185)
