This is the initial commit with system build, sysbuild. Using CMake as infrastructure together with the Zephyr sysbuild allows us to support a convenient way of building a sample and allow for extra images to be built as part of a larger system. It uses Kconfig for configuration of image builds. This allows for future extension with additional build images. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
