avformat: add a disposition field to AVStreamGroup

Browse Source 
The existing (and upcoming) available group types are meant to combine several
streams for presentation, with the result being treated as if it was a stream
itself.
For example, a file could export two stream groups of the same type with one of
them as the "default".
