quic: connection lifetime management

Manage the closing and draining states.

A connection enters the closing state after sending a CONNECTION_CLOSE
frame to terminate the connection.

A connection enters the draining state after receiving a
CONNECTION_CLOSE frame.

Handle retransmission of CONNECTION_CLOSE frames when in the
closing state, and properly ignore received frames when in the
draining state.

RFC 9000, Section 10.2.

For golang/go#58547
