jpeg2000parse + openjpeg: Switch striped mode to its own caps

Browse source 
It's not compatible with any other element that use the non-striped
mode. In addition, in this mode, we require that every frame have the
same number of stripes or that the MARKER bit be present, which is
different from the other
formats too.
