Update oghttp2 to close streams above a received GOAWAY's last_stream_id.

This CL causes oghttp2 to respond to the receipt of a GOAWAY by:
  - Closing active streams in its stream map above the GOAWAY's last_stream_id.
  - Avoiding sending frames with stream ID values above the last_stream_id.
These two changes handle cases where request HEADERS (or other frames for a
stream) have already been enqueued at the time a GOAWAY is received, while also
preventing subsequent enqueues for these active streams (by closing them).

This CL does not handle the cases of new or pending streams, i.e., does not
prevent subsequent requests or the start of requests that have been queued as
pending. These cases will be handled in follow-up cl/439616811.

This change increases oghttp2 parity with nghttp2.
