  Changed paths:
    M include/internal/quic_fc.h
    M ssl/quic/quic_fc.c
    M ssl/quic/quic_stream_map.c
    M ssl/quic/quic_txp.c
    M test/quic_fc_test.c

  Log Message:
  -----------
  Keep track of connection credit as we add stream data

If a single packet contains data from multiple streams we need to keep track
of the cummulative connection level credit consumed across all of the
streams. Once the connection level credit has been consumed we must stop
adding stream data.

Fixes #22706
