feat(CMYK): add API color model and profile methods to project

Browse Source 
API allows to define a color model without a color space. If both are
set, consistency between defined color model and color space one is
checked (only in Qt version 6.8.0 or greater because it's not possible
to retrieve color model from color space before that)
