Pass a handshake message content CBS to TLSv1.3 receive handlers.

This avoids every receive handler from having to get the handshake message
content itself. Additionally, pull the trailing data check up so that each
receive handler does not have to implement it. This makes the code more
readable and reduces duplication.
