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.

Support referencing module directories by name in CONF_FILE,
OVERLAY_CONFIG, and DTC_OVERLAY_FILE so that projects can reference
overlay files in arbitrary modules.
Verified by passing all the following tests:
./scripts/twister -T tests/cmake/overlays/
Fixes#41830

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.

Fixes: #40389
This commit aligns the use of the following Zephyr build variables:
- CONF_FILE
- DTC_OVERLAY_FILE
- OVERLAY_CONFIG
- WEST_DIR
- ZEPHYR_BOARD_ALIASES
- ZEPHYR_EXTRA_MODULES
- ZEPHYR_MODULES
so that they can be set in same manner and with same order of
preference.

Create a cmake/modules folder containing all Zephyr CMake modules.
All Zephyr cmake files that are included from boilerplate are now
converted into CMake modules which can be individually loaded.
The Zephyr CMake package is updated to support loading of individual
CMake modules using the COMPONENTS argument to `find_package(Zephyr)`.
If the COMPONENTS argument is not specified, the default Zephyr build
system will load.
If COMPONENTS is specified then, only those components and the
dependencies will be loaded.
If a Zephyr CMake module depends on another CMake module which has not
been loaded, it will automatically be loaded.
This allows us to modularize and reuse individual parts of the Zephyr
CMake build system in a more flexible way in future.
Such usage could be:
- Higher livel multi image build system
- Invocation of individual components, for example dts processing by
twister without loading all build code
- Doc build
- Unittesting
With this new CMake package and CMake module scheme then direct
sourcing of boilerplate.cmake has been deprecated.
