Selecting a kit with variant

[eMKa94]

I'm working mostly on embedded projects where, besides the cross-compilation config, I also have the variants for unit tests and sometimes some host console applications within a single project. I often have a variant for "application type" where I can choose if I'm building the firmware or unit test etc... Swapping between those variants also requires manually changing the selected kit and if
only I select a new variant ( or KIT ) the configuration starts and it ends up with errors because for example I change to the firmware build variant with native compiler kit selected or change the kit to cross-compiler but the variant was set to build unit tests for host machine... In my imagination, it will be perfect if I will be able to point the correct kit when defining the variant option in cmake-variants.json
