typefindfunctions: Extend MCC typefinder to also cover version 2.0

Both versions are basically the same, but version 2.0 also allows
60000/1001 as framerate and allows to specify the field and line number
for each payload.

Put the major version into the caps so that elements can limit via caps
negotiation which versions they can support.
