This commit introduces the possibility of a sample to locate
configuration files for extra images that are used when building with
MCUboot.
This allows use-cases where a sample, A, want to include MCUboot but has
adjustments to the default MCUboot configuration.
By adding a Kconfig fragment `<sample>/sysbuild/mcuboot.conf`, then that
fragment will be used together with the default configuration for
MCUboot.
It is also possible to completely replace the MCUboot configuration.
This is done by creating `<sample>/sysbuild/mcuboot/` folder.
This folder will then be used as the `APPLICATION_CONFIG_DIR` when
building MCUboot.

This commit loads the CMakeCache of Zephyr projects.
This allows sysbuild to fetch information from Zephyr projects into
sysbuild itself.
This commit is a first step in the process of sharing more knowledge
between images and sysbuild, and pave the way for closer sharing of
settings between images.

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.

This commit introduces image signing by adding the possibility to
specify algorithm and signing key for sysbuild images.
It introduces Kconfig setting to specify signing algorithm and key file.
It will default the signing key to the default key provided by MCUBoot
if no key has been specified.
When signing is enabling, the signature key will be passed to the
application so the build system can sign the image as post build step.

Support creation of domains.yaml to support
`west <build|flash|debug> --domain` when working with sysbuild multi
image.
Each Zephyr based image is added to list of domain that can be handled
by the Zephyr west extension commands.

This commit adds CMake and Kconfig files needed to build MCUboot as
an extra image using SYSBuild.
Building an application with MCUBoot using SYSBuild allows users to
build both images using a single build.

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.
