"Populate" is ambiguous here: does that mean set, or append? The
answer is "append", so use that to be clearer. Be extra clear where
we're looking in as well.

Load image kconfig setting into image target properties.
This allows sysbuild to evaluate and check image configuration as part
of CMake invocation.
sysbuild_get() is updated to support reading of CMake cache or Kconfig
settings for an image.

The signature of import_kconfig() take two mandatory arguments and one
optional:
> import_kconfig(<prefix> <kconfig_fragment> [<keys>])
but has been implemented in such a way that it loops all arguments after
the two mandatory args and sets the same list on those.
Fix this error by only setting the created variables on the third and
optional argument if it exists.

Introduce a `test_sysbuild()` function.
This function is intended to be used by samples that are dependent on
sysbuild. This function allows such samples to test if sysbuild was used
in the build process, and when sysbuild is not used, then print a
warning to the user, or even fail the build.
This is useful for samples that have two parts to function properly, for
example samples that needs to be build and flash on two or more cores.

Fixes: #47588
Kitware decided to fail compiler tests of single options if the
compiler reported only a warning and not an error:
github.com/Kitware/CMake/commit/f745e0497ee71d35fd1b3524b1636a72da76c266
which affects CMake 3.23.0 and 3.23.1
This change was later reverted in CMake >=3.23.2 and >=3.24.0
github.com/Kitware/CMake/commit/4941887d7defecb3016d2bd94d3a45754251ca56
Although the immediate issue is related to CMake, and has been fixed
reverted in later releases, then it still makes sense to be able to
group compiler options together that generally are depending on each
other to function correctly.
This commit introduces the possibility to group compiler options which
must be tested together.
It uses same approach as
> add_compile_options("SHELL:<option1> <option2> ...")
Usage:
> check_set_compiler_property(PROPERTY <property>
> "SHELL:<option1> <option2> ..."
> )
Will test the option together.

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.

A cache variable specified by the user as `-DVAR=value` will have the
type UNINITIALIZED in the CMake cache.
Later CMake re-runs will execute the line:
set(${variable} ${CACHED_${variable}} CACHE STRING
"Selected ${variable_text}" FORCE)
This will update the cache type from UNINITIALIZED to STRING and thus
may be picked up by other tools as a change.
To ensure the type is initialized to string, this is added:
set(${variable} ${${variable}} CACHE STRING "Selected ${variable_text}")
This code will not change the value of an existing CMake cache variable
because there is no FORCE, but what it will do is to update the cache
variable type to STRING.
As part of this, include the existing parent scope setting of variable
inside the `if(DEFINED ...)` as there is no reason to clear a variable
there is not having a value.

Fixes: #40389
This commit implements zephyr_get(<variable>).
The purpose of zephyr_get(<variable>) is to ensure a uniform way to
handle variables which can be defined as:
- CMake cache variable, for example `-D<var>=<value>`.
- Environment variable
- Locally in CMakeLists.txt file before `find_package(Zephyr)`
It furthermore ensures that if an environment setting hides a local
setting then a warning is printed.
using
zephyr_get(<var>)
removes the need for constructs like:
set_ifndef(<var> "$ENV{<var>}")
set(<var> ${<var>} CACHE PATH "")
if(NOT DEFINED <var>)
set(<var> $ENV{<var>})
endif()
if (NOT DEFINED ENV{<var>})
message(FATAL_ERROR <error>)
endif()
and also ensures identical preference order for variables used in Zephyr
1. cache
2. environment
3. local scope var
It also ensures the variables supported through environment can also be
set using `-D<var>=<value>`

zephyr_library_compile_options() was attempting to create
unique hashes for compile options in order to prevent creating
them multiple times. However, it was only using the first
argument to create the hash, so if multiple libraries had
different compile options but the first line was the same,
the second set would be mistaken for the first set and would
actually be passed the first set during compilation instead
of its own set.
The fix should be to use the entire compile options argument
list to create the hash so they should only match if the entire
options list is exactly the same.
This is a continued fix for #43835

This patch is doing two things:
- it is removing the fallback on the path. This is not possible anymore
since the DT binding file is now actually requiring the
'zephyr,memory-region' property to be present from which the region
name is obtained.
- it is sanitizing the name when CONFIG_CMAKE_LINKER_GENERATOR is used
or not.

COPY/NOCOPY flag was added to the end of the string with ':'
as separators. The python script then split the line on ':'
which breaks on Windows build because the string was
[MEM]:[FILE]:[COPY]
In windows you will have 'c:\' in the file path so the
line.split() in script will split on the 'c:'.
Move the COPY/NOCOPY to:
[MEM]:[COPY/NOCOPY]:[FILE]
Note that the comments at top of gen_relocate_app.py also
indicates this format.

Currently when a node has a 'zephyr,memory-region' compatible and a
'zephyr,memory-region' string property, a new memory region is created
in the linker script.
Having a memory region without a section to place variables in could be
not that useful. With this patch we extend the memory-region mechanism
to also create sections.
The user can then place variables in the sections as usual by using for
example the GCC attributes.

In zephyr_library_compile_options() the existence of the compile
options interface library is checked and function returns if it already
exists. This results in #43835 meaning two libraries cannot add the
same option.

library and link this to the Zephyr library.

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.
