Rework GOAWAY emission handling at the HTTP/3 layer. Previously, h3c member <id_goaway> were updated during the connection on each new streams attach. This ID was finally reused when a GOAWAY was emitted. However, this is unnecessary to keep an updated ID during the connection lifetime. Indeed, <largest_bidi_r> QCC member can be used for the same purpose. Note that this is only useful for the frontend side. For a client connection, GOAWAY contains a PUSH ID, thus 0 can be used for now. Thus, <id_goaway> in h3c is renamed <id_shut_l>. Now it is only sent when the GOAWAY is emitted. This allows to reject any streams with a greater ID. This approach is considered simpler. Note that <largest_bidi_r> is not strictly similar to the obsolete <id_goaway>. Indeed, if an error occurs before the corresponding stream layer allocation, the former would still be incremented. However, this is not a real issue as GOAWAY specification is clear that lower IDs are not guaranteed to being handled well, until either the stream is closed or resetted, or the whole connection is teared down.
