qtdemux: consider 3gpp style tag parsing in some more cases

3GPP specs define a number of tags along with precise layout. While these
are normally expected to be found in a container whose major brand is a
3GPP brand, this may also happen when a 3GPP brand is only mentioned as a
compatible brand.  Apply some checks, heuristic and fallbacks to extract
such tags as well.
