Switch to using SSL_get0_certificate_types for client auth.

Switch to using SSL_get0_certificate_types for client auth.

Upstream added SSL_get0_certificate_types while we added
SSL_get_client_certificate_types in parallel. Switch to upstream's API.

File net/socket/ssl_client_socket_openssl.cc (right):

https://codereview.chromium.org/415853002/diff/1/net/socket/ssl_client_socket...
net/socket/ssl_client_socket_openssl.cc:1343: SSL_get0_certificate_types(ssl,
&client_cert_types);
Even though this is upstream's API, it does have the downside of going through
SSL_ctrl and thus not having any type-checking. ssl2_ctrl is gone now and
dtls1_ctrl is a tiny tiny wrapper over ssl3_ctrl. Perhaps we should start
ripping all the SSL_ctrl switch-case + macro pairs into individual functions?
Would have to be careful about any consumers that call the SSL_ctrl directly,
and any consumers which #ifdef on the macro. But apart from that....
