b03d27cca3 toolchain: esp32: support esp32s3 in 'espressif' toolchain
CROSS_COMPILE_TARGET is defined based on CONFIG_SOC selected. So far
'esp32s3' SoC was not taken into account, so building Zephyr with
'espressif' toolchain (the only one supported for now) is was not possible
out of the box.

Add 'CROSS_COMPILE_TARGET_xtensa_esp32s3' CMake variable, same as it is
done for other SoC specific variables. That way toolchain paths are
automatically figured out and building succeeds.

45b25e5508 cmake: dereference ${check} after zephyr_check_compiler_flag() call
Follow-up: #53124

The PR#53124 fixed an issue where the variable `check` was not properly
dereferenced into the correct variable name for return value storage.
This was corrected in 04a27651ea.

However, some code was passing a return argument as:
`zephyr_check_compiler_flag(... ${check})`
but checking the result like:
`if(${check})`
thus relying on a faulty behavior of code updating `check` and not the
`${check}` variable.

Fix this by updating to use `${${check}}` as that will point to the
correct return value.

728230a241 cmake/compiler: Limit warning flag usage to compatible toolchains
New C++ versions have deprecated "register" variables and restricted
"volatile" semantics, so new gcc's will emit warnings when they see
that syntax.  Zephyr uses both in our C headers (though we should
probably get rid of register and unify with C++'s volatile model), so
we're disabling the resulting warnings.

But OLD gcc variants (like xcc, sigh) don't understand new -Wvolatile
and -Wregister on the command line, so they get confused.  Limit the
uses to the standard versions for which gcc would emit warnigns; xcc
doesn't support those anyway.

2d12766e78 toolchain: oneApi: Fix support and update for 2023.0.0 release
The oneApi support has bit rotten since it was first introduced.  Update
the support to function with the latest 2023.0.0 release and add a
check to only support that version or newer for now.  Versions before
2021.2.0 have linker script failures.

Various fixes made:
* In the 2023.0.0 release, various binaries are in a llvm-bin path so
  add support to search in that path.  This replaces the python search
  path that much older versions needed.
* newlib isn't supported with oneApi so set TOOLCHAIN_HAS_NEWLIB to
  OFF to match that.
* 2023.0.0 doesn't back llvm-nm, so use binutils version.  This
  is expected to be fixed in 2023.1.0 release so add a check to
  handle either case.
* Update compiler flag check based on clang to also support
  CMAKE_C_COMPILER_ID of "IntelLLVM" as that is how the oneApi toolchain
  reports itself.

91902c5fd4 cmake: add sparse support to the new SCA infrastructure
Sparse support was original introduced in #43776.

This commit introduces sparse support as part of Zephyr SCA tool
infrastructure.

The implementation in this commit has some benefits over existing
support:
- It does not required users to set `REAL_CC` in environment before
  invoking build command.
  This reduces risk of user mistakes, such as
  - REAL_CC being different from CMAKE_C_COMPILER.
  - User running CMake in one terminal / environment where REAL_CC is
    defined but invoking the build command in a different terminal /
    environment where REAL_CC is not defined or defined differently.
- It improve user experience as the user no longer has to define /
  re-define REAL_CC when building for different architecture, like
  switching from arm to xtensa, as this is now handled in CMake.
- CMAKE_C_COMPILER is not overwriting, this can be important for other
  tools which calls the C compiler for pre-processing purposes, such
  as devicetree and linker script generation.

cb690ec56e cmake: implement build infrastructure for supporting SCA tools.
Static code analyser (SCA) tools are important in software development.

CMake offers built-in support for some tools, such as cppcheck and
clang-tidy.

Other tools, such as sparse, are not directly supported.

This commit provides a uniform way for users to specify a supported
SCA using `ZEPHYR_SCA_VARIANT=<tool>` which is consistent with how
toolchains are specified.
ZEPHYR_SCA_VARIANT can be set using `-D` or in environment.

Support for an SCA tool is done in `cmake/sca/<tool>/sca.cmake`.
SCA_ROOT can be used to specify additional search paths when looking up
implementation for a tool. SCA_ROOT can also be specified in
`zephyr/module.yml` as setting. This makes it possible to provide SCA
tool implementation as part of a Zephyr module.

ac5d45a080 build: userspace: No merge globals
Add a compiler option to not merge globals. gen_kobject_list.py
is not capable of distinguish addresses of merged objects. The script
itself does not look wrong. The dward specification says that the
attribute DW_AT_location with opcode DW_OP_addr encodes a machine
address and whose size is the size of an address on the target machine
but for merged objects the address is longer, not clear why.

10e85bf764 cmake: update API for zephyr_code_relocate to support relocating libraries
Update API for zephyr_code_relocate to support cmake generator expressions,
as well as relocating libraries.

zephyr_code_relocate can now accept a target name to the LIBRARY argument,
which will be converted into a set of source files from that
target to relocate.

Alternatively, files can be passed as a space separated list
or CMake generator expression. This allows users more
flexibility when relocating files. Glob matching functionality is still
available, although the preferred method to do this would now be:

file(GLOB relocate_sources "src/*.c")
zephyr_code_relocate(FILES ${relocate_sources} LOCATION <location>)

Note! This commit breaks support for zephyr_code_relocate until in tree
usages of the API are updated to the new format.

e3d877f811 rtio: Userspace support
Add support for userspace with RTIO by making rtio and rtio_iodev
k_objects. As well as adding three syscalls for copying in submissions,
copying out completions, and starting tasks with submit.

For the small devices Zephyr typically runs on one of the most important
attributes tends to be low memory usage. To maintain the low footprint of
RTIO and its current executor implementations the rings are not shared with
userspace. Sharing the rings it turns out would require copying submissions
before working with them to avoid TOCTOU issues.

The API could still support shared rings in the future so that a
kernel thread could directly poll, copy, verify, and start the submitted
work. This would require a third executor implementation that maintains its
own copy of submissions similiar to how io_uring in Linux works.

e0fb04458f cmake: sysbuild: import image kconfig settings to image target
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.
