crypto/tls: check verifiedChains roots when resuming sessions

crypto/tls: check verifiedChains roots when resuming sessions

When resuming TLS sessions, on the server and client verify that the
chains stored in the session state (verifiedChains) are still acceptable
with regards to the Config by checking for the inclusion of the root in
either ClientCAs (server) or RootCAs (client). This prevents resuming
a session with a certificate chain that would be rejected during a full
handshake due to an untrusted root.
