Add const overloads for QColor::getCmyk and QColor::getCmykF

Align the constness of QColor::getCmyk and QColor::getCmykF with the
rest of the family (QColor::getRgb etc.) by adding overloads. The
non-const methods could be removed with the next major release as that
will break binary compatibility.
