Torsten Rasmussen 88ae9cbb9d cmake: extend zephyr_get() to handle build configurations from sysbuild
Enhance sysbuild controlled configurations.

The current scheme of passing settings using `-D` on the CMake
invocation is vulnerable to quoting and lists.

With `zephyr_get()` in place as a uniform way of handling user
controlled settings (CMake cache / environment / CMake local variable)
we have a mechanism in place for a cleaner handling of sysbuild
controlled settings.

This improves the robustness of variable passing and add the same cleans
up and simplifies the logic in sysbuild.

The Kconfig Zephyr CMake module has been updated accordingly so that
CONFIG settings are taken from the sysbuild shadow cache when sysbuild
is used as higher level build system.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
