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.
