Fixes #2344
Specifically,

• Copies the ClientRandom on server side.
• Copies the ClientEarlyTrafficSecret on server side.
• Copies the ClientRandom on client side when 0-RTT is used.

Testing

• Manual testing with quicinteropserver to ensure the ClientRandom is logged.
• New automated tests.

We should write a test that verifies the client and server secrets & random match.

Gonna need to think about this a bit. It would involve recreating some TLS logic, and what exactly what it be compared against?
The test hooks might not exist for this yet.

Just take a simple handshake test, update both sides to grab the secrets. After the handshake completes, compare the client and server secrets.
