crypto/tls: don't reverify but check certificate expiration on resumption

We used to inconsistently run certificate verification on the server on
resumption, but not on the client. This made TLS 1.3 resumption pretty
much useless, as it didn't save bytes, CPU, or round-trips.

This requires serializing the verified chains into the session ticket,
so it's a tradeoff making the ticket bigger to save computation (and for
consistency).

The previous behavior also had a "stickyness" issue: if a ticket
contained invalid certificates, they would be used even if the client
had in the meantime configured valid certificates for a full handshake.

We also didn't check expiration on the client side on resumption if
InsecureSkipVerify was set. Again for consistency, we do that now.

Also, we used to run VerifyPeerCertificates on resumption even if
NoClientCerts was set.

Fixes #31641
