460512 Update LittleCMS to 2.14rc1 and upgrade its CMake toolchain
This MR updates LittleCMS to 2.14rc1 and applies a recent fix (https://github.com/mm2/Little-CMS/commit/aa7f240da8dc27a0bb082462889cca9026bf2b27) to the bug referenced below.
I've also taken the opportunity to modernize @rempt's original CMake toolchain.
Test Plan
Build LittleCMS and Krita. I've tested it on all compilers under Windows, so it'd be great if macOS, Linux and Android could be checked too.
