the list of blendmodes that perform channel-inversion in CMYK color space

Here is the list of blendmodes which are not invariant to color channel inversion, therefore they cannot work in CMYK properly. These modes automatically invert the channels before blending when used for CMYK color space.

This is a behavior-change in Krita 5.2
