GUI: add CMYK painting support
This commit adds a CMYK 8bpp format to QImage. The idea is to enable the
transport of CMYK images inside Qt, for instance to be loaded/saved from
files or painted on CMYK capable paint devices (e.g. PDF).
Also, rasterization support *from* a CMYK image is added (on top of a
RGB surface), as well as CMYK image scaling/conversion.
Conversion and rasterization between CMYK and RGB isn't particularly
optimized nor it honors any colorspaces yet. The overall idea is to
match 1:1 the existing behavior of CMYK QColor (which get naively
changed to RGB; there isn't colorspace support in QPainter yet).
There are no plans to add rasterization *towards* CMYK.
Image save/load in native CMYK formats will be added in future commits.
This work has been kindly sponsored by the QGIS project
(https://qgis.org/).
[ChangeLog][QtGui] Support for 8-bit CMYK images has been added.
