color-lcms: add translate_curve_element_LUT()
Currently in translate_curve_element() we always translate the curve
into a LUT. But in the future we'll be able to translate the curves to
parametric ones.
So move the current code to a new function
translate_curve_element_LUT(), so that in translate_curve_element() we
are able to call one of the two functions (_LUT() or _parametric()).
No behavior changes, just preparation for the upcoming patches.
