In some scenarios nb_tracks isn't the same as nb_streams, so a given id may end
up being used for two separate streams.
e.g. when muxing an IAMF track followed by a video track, if the IAMF track
consists of several streams, the video track would end up having an id of 2,
which may also be used by one of the IAMF streams.

The semantics for the field are different than the one in AVCodecParameters,
so use the name defined in the IAMF spec to prevent confusion.
