When using picolibc from the toolchain, we need to use the standard include

Add toolchain picolibc to the list of cases for which this is the case.

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.

In some architectures the linker performs global optimization relaxing
address modes and changing intructions in the output object file. This
is a problem when userspace is enabled since it assumes that addresses
won't change after certain build stage. In no supported architectures
this option is ignored.

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.

This adds a choice of three different libc API buffer overflow detection
modes:
* None
* Compile-time
* Compile-time and Run-time
These correspond with the clang/gcc _FORTIFY_SOURCE modes (0/1/2).
_FORTIFY_SOURCE depends on compiler optimizations and require libc support
which the minimal C library doesn't include, so _FORTIFY_SOURCE is disabled
by default in those cases. Native tooling might also enable
_FORTIFY_SOURCE, so don't enable it by default in that case either.

The commit f10fa0dea8 mapped the
Cortex-R52 processor type to use the "VFPv3" FPU type, but the
toolchain requires the "FPv5" FPU type and refuses to assemble
floating-point instructions when the "VFPv3" FPU type is specified.
This commit updates the build script to specify the FPU type of
`fpv5-sp-d16` when the processor is configured with a single-precision
FPU, and `neon-fp-armv8` when the processor is configured with a
double-precision + Advanced SIMD-capable FPU.
Note that the `fp-armv8` FPU type is an alias for double-precision FPv5
with 32 double-precision registers (refer to the GCC
`gcc/config/arm/arm-cpus.in` for more details); NEON is always
specified in case of a double-precision configuration because the
Cortex-R52 can only be configured as such.

This function is intended to be used by samples that are dependent on

in the build process, and when sysbuild is not used, then print a

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.

The `ARCH` init level was added to solve a specific problem, call init
code (SYS_INIT/devices) before `z_cstart` in the `intel_adsp` platform.
The documentation claims it runs before `z_cstart`, but this is only
true if the SoC/arch takes care of calling:
```c
z_sys_init_run_level(_SYS_INIT_LEVEL_ARCH);
```
Which is only true for `intel_adsp` nowadays. So in practice, we now
have a platform specific init level. This patch proposes to do things in
a slightly different way. First, level name is renamed to `EARLY`, to
emphasize it runs in the early stage of the boot process. Then, it is
handled by the Kernel (inside `z_cstart()` before calling
`arch_kernel_init()`). This means that any platform can now use this
level. For `intel_adsp`, there should be no changes, other than
`gcov_static_init()` will be called before (I assume this will allow to
obtain coverage for code called in EARLY?).

We have cases where some devices needs to be initialized very early and
