Refactor TlsHandshaker classes
QuicCryptoClientConfig and QuicCryptoServerConfig each own an SSL_CTX,
which is currently created by TlsHandshaker. Those crypto config classes
can't take a dependency on TlsHandshaker (because TlsHandshaker depends on
classes have a dependency in the other direction), resulting in the SSL_CTX
being passed into the crypto config constructors. The SSL_CTX shouldn't be
exposed like this, as it's essentially an implementation detail of the
crypto handshake.
This CL splits TlsHandshaker in two. TlsConnection (and its subclasses) are
in quic/core/crypto, and handle the callbacks from BoringSSL. In turn, it
passes the implementation of those callbacks to a delegate. TlsHandshaker
implements this delegate and owns the TlsConnection.
