This runs through much the same code as the TLS 1.3 bits, though we use
a different hint field to avoid mixups between the fields. (Otherwise
the receiver may misinterpret a decryptPSK hint as the result of
decrypting the session_ticket extension, or vice versa. This could
happen if a ClientHello contains both a PSK and a session ticket.)
