When using the code and data relocation feature, every relocated symbol
would be marked with `KEEP()` in the generated linker script. Therefore,
if any input files contained unused code, then it wouldn't be discarded
by the linker, even when invoked with `--gc-sections`.
This can cause unexpected bloat, or other link-time issues stemming from
some symbols being discarded and others not.
On the other hand, this behavior has been present since the feature's
introduction, so it should remain default for the users who rely on it.
This patch introduces support for `zephyr_code_relocate(... NOKEEP)`.
This will suppress the generation of `KEEP()` statements for all symbols
in a particular library or set of files.
Much like `NOCOPY`, the `NOKEEP` flag is passed to `gen_relocate_app.py`
in string form. The script is now equipped to handle multiple such flags
when passed from CMake as a semicolon-separated list, like so:
"SRAM2:NOCOPY;NOKEEP:/path/to/file1.c;/path/to/file2.c"

Functions `zephyr_linker_dts_memory()` and `zephyr_linker_dts_section()`
are described as defining a memory region or section based on a DT node,
as long as it "exists and has status okay". However, only the existence
of the node is actually checked, using `dt_node_exists()`. To fix that,
employ `dt_node_has_status()` instead, which can check both conditions.
The status check is important, because both functions require the given
DT node to contain a `zephyr,memory-region` property (not to be confused
with the compatible string). This property is required by the associated
binding as well, but required properties can be omitted from nodes which
don't have status "okay". In those cases, edtlib won't raise an error,
and neither should CMake, because those nodes should be ignored.
Speaking of that property, add a missing error check for it as a bonus
(tucked behind the status check, of course).

This function has been working fine for parsing Kconfig fragments as
processed by Kconfiglib, but it can be made more robust for parsing
fragments from other sources, including handwritten ones.
Previously, Kconfig fragment lines of the form `# CONFIG_FOO is not set`
were ignored entirely, while lines of the form `CONFIG_FOO=n` would set
the corresponding CMake variable or target property to a literal `n`.
However, Kconfiglib treats both equivalently - as assignments to `n` -
so `import_kconfig()` should too.
Due to the fact that `.config` files output by Kconfiglib always show
disabled options as `# CONFIG_FOO is not set` (which was being ignored),
existing CMake code expects `CONFIG_FOO` to be unset. To avoid breakage,
the variable/property will now be unset explicitly by `import_kconfig()`
when it encounters either representation of `CONFIG_FOO=n`.
Moreover, for bool and tristate symbols, Kconfiglib accepts assignments
like `CONFIG_FOO=yeah`, `CONFIG_FOO=maybe`, or `CONFIG_FOO=nope`, and it
transforms the value of `CONFIG_FOO` into `y`, `m`, or `n` respectively.
This effect is now replicated in CMake.

The syscall generation phase parses all header files to look
for potential syscalls, and emits all the relevant files to
enable syscalls. However, this results in all the syscall
marshalling functions being included in the final binary.
This is due to these functions being referred to inside
the dispatch list, resulting in ineffective garbage
collection during linking. Previous commits allows each
drivers and subsystems to specify which header files
containing syscalls are relevant. So this commit changes
the syscall generation to only include the syscalls needed
for the build in the syscall dispatch list and removing
various bits related to that. This allows the linker to
garbage collect unused syscall related function, and thus
reducing final binary size.

Snippets provides the possibility of defining EXTRA_DTC_OVERLAY_FILE and
EXTRA_CONF_FILE in snippets.
Snippets must co-exist with existing infrastructure of
EXTRA_DTC_OVERLAY_FILE and EXTRA_CONF_FILE, and a user specifying a
snippet must be able to specify extra files for adjusting the snippet.
This means that if the following is specified:
`-DSNIPPET=some_snippet -DEXTRA_CONF_FILE=extra.conf`
then `extra.conf` may contain adjustments to the snippet.
Similar to sysbuild. Imagine a sysbuild controlled image uses a default
snippet for building, by ensuring that any extra
`-D<image>_EXTRA_CONF_FILE=extra.conf` arguments takes precedence over
the snippet we allow users to make adjustments if they need.
This commit introduces a snippets scope where snippet scoped variables
can be set with `zephyr_set()` and then `zephyr_get()` will take the
snippet scoped variables into consideration before returning.
Adjust calls to `zephyr_get(EXTRA_DTC_OVERLAY_FILE)` and

Adding the possibility to have the list returned in reversed order when
using `zephyr_get(... MERGE).
`zephyr_get(... MERGE)` creates a list which populates the content based
on variable settings in the following scopes, in this order:
sysbuild, cache, environment, local.
This works well for lists where content first in list has highest
precedence, such as ROOTs settings.
However, for settings where the value last in the list will overwrite
values earlier in the list, we want the list to be reversed, examples
of such can be CONF_FILE, OVERLAY_CONFIG, DTC_OVERLAY_FILE, where the
content of the file last in the list will overrule the content from an
earlier file.
So to ensure that a DTC_OVERLAY_FILE defined as cache takes precedence
over an env or local scope variable the possibility of reversing the
list must be available.

This commit extends zephyr_get() to support multiple variable names to
be fetched into a single variable.
Example:
zephyr_get(FOO VAR FOO_A FOO_B FOO_C)
will lookup each FOO_A, FOO_B, FOO_C for supported scopes and return
the value in FOO of the first scope encountered having one of the
variables defined.
If MERGE is specified, then all scopes for all vars are looped and the
variable values are merged into FOO and returned.
This functionality will allow to deprecate user-facing settings while
ensuring that both the new and deprecated variables are considered
in zephyr_get() and also taking into consideration the scope with
highest precedence.
This allows Zephyr CMake to do:
zephyr_get(FOO VAR FOO DEPRECATED_FOO)
zephyr_get(BAR MERGE VAR BAR DEPRECATED_BAR)
This allows support of old and new setting for a given number of
releases.

A cache variable specified by the user as `-DVAR=value` will have the

To ensure the type is initialized to string, this is added:

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.
