QUIC: optimized immediate close.
Previously, before sending CONNECTION_CLOSE to client, all pending frames
were sent. This is redundant and could prevent CONNECTION_CLOSE from being
sent due to congestion control. Now pending frames are freed and
CONNECTION_CLOSE is sent without congestion control, as advised by RFC 9002:
Packets containing frames besides ACK or CONNECTION_CLOSE frames
count toward congestion control limits and are considered to be in flight.
