quic: add a type tracking sent values

Any given datum communicated to the peer follows a state machine:

  - We do not need to send the this datum.
  - We need to send it, but have not done so.
  - We have sent it, but the peer has not acknowledged it.
  - We have sent it and the peer has acknowledged it.

Data transitions between states in a consistent fashion; for example,
loss of the most recent packet containing a HANDSHAKE_DONE frame
means we should resend the frame in a new packet.

Add a sentVal type which tracks this state machine.

For golang/go#58547
