v4l2object: append non colorimetry structure to probed caps
requested to merge Shengqi.Yu/gstreamer:v4l2object-append-non-colorimetry-structure-to-probecaps into main
If the stream has a special colorimetry that is not in the colorimetry list, it will cause negotiation to fail. We should allow passing any colorimetry, so add an extra structure without the colorimetry field. This is another solution in merge request !4409
