gfe-relnote: In QUIC, implement GetHandshakeState() in various handshakers. Not used yet, not protected.
GetHandshakeState() will be used to retrieve current handshake state, and handshaker is the only source of this information. But caller can choose to latch handshake state for performance purpose.
