This commit adds the filtering DECIM Q15 test patterns and
implementations for the CMSIS-DSP 1.9.0.

This commit makes the tests for the partial convolution functions
(`arm_conv_partial*`) optional because these functions have computation
precision-related issues (tested with CMSIS-DSP 1.9.0, which is part of
the CMSIS 5.8.0 release).
The partial convolution functions (especially the fast variants) can
return very low-precision results (as low as 14dB SNR) under certain
configurations.
This issue will be further investigated and reported to the upstream
CMSIS developers.
Once this issue is fixed upstream, revert this commit in order to make
the partial convolution tests run all the time.

This commit updates the CMSIS-DSP configurations for the CMSIS-DSP

This commit adds the half-precision (16-bit) floating-point
configurations to the ARM AArch32 architectures.
Enabling CONFIG_FP16 has the effect of specifying `-mfp16-format`
option (in case of GCC) which allows using the half-precision floating
point types such as `__fp16` and `_Float16`.
Note that this configuration can be used regardless of whether a
hardware FPU is available or supports half-precision operations.
When an FP16-capable FPU is not available, the compiler will
automatically provide the software emulations.

There was a typo that snuck into the bbram driver for npcx.
Fix the driver and update the Kconfig to automatically include the
driver if the compatible string exists in the dts. This ensures that
the driver is built when building the npcx evbs.

PR #36996 disabled running mem_protect/stack_random test on qemu_riscv32
platform because of this test consistently failing on said platform.
This test starts new threads in equal time intervals, and because of
that we get repeating values after performing the modulus operation when
calculating the stack pointer address.
This can be solved by changing the value of the _RAND32_INC constant
that is used to increase the value returned by the timer-based PRNG.
This commit decreases the value of the mentioned constant from
1000000013U to 1000000003U.
Fixes#37006.

This commit adds an additional test case for several kernel test suites
to ensure that the linker script generator is working correctly for a
subset of the Zephyr test suites.
The ensures that the basic functionality of the linker script generator
is working while still keep the performance impact on CI at a minimal
level.
Using the kernel tests is a trade-off between testing coverage of the
linker script generator and the time it takes to complete CI.
The kernel tests is considered to have the broadest coverage of various
features important for the generated linker script.

The stub file threading_weak.c has been added containing weak stub
implementation of threading related kernel functions.
The file is needed for armlink.
When linking with armlink the linker will resolve undefined symbols for
all undefined functions even if those functions the reference the
undefined symbol is never actually called.
This file provides weak stub implementations that are compiled when
CONFIG_MULTITHREADING=n to ensure proper linking.

Support for ARM Compiler C library.
This commit add support for the ARM Compiler C libary in:
- Kconfig
- libc/armstdc
A new Kconfig symbol is added to allow a toolchain to specify if they
support linking with the minimal C library.
Also the CMake variable `TOOLCHAIN_HAS_NEWLIB` is exported to Kconfig
so that CONFIG_NEWLIB_LIBS can only be enabled if the toolchain has
newlib.
The armclang toolchain selects the CMake scatter file generator and
disables support for the LD linker template which is not supported by
armlink.
For the ARM Compiler C library, a corresponding lib/libc/armstc/ folder
with a minimal implementation to work with the ARM Compiler C library
is added.

This commit introduces armlink steering file.
A steering file in armlink allows Zephyr to keep using existing linker
symbols defined in ld scripts and used throughout the code tree.
The steering file is generated at build time in order to resolve Zephyr
linker symbols to their corresponding armlink symbols.
As example, Zephyr defines __ramfunc_start which corresponds to the
armlink auto defined Image$$ramfunc$$Base symbol.
Or __init_PRE_KERNEL_1_start which corresponds to Image$$init_0$$Base.

The default armlink signature uses `--list=<TARGET_BASE>.map`, but in
Zephyr we uses a different name for the map file, therefore we need to
specify a custom link executable signature.
This is done in the linker specific flags file:
cmake/linker/armlink/linker_flags.cmake

When using ARMClang linker and scatter files (armlink) then all
libraries are linked as object libraries using `$<TARGET_OBJECTS:lib>`.
CMake version 3.20 only has limited support for such linking:
> Referencing $<TARGET_OBJECTS> in target_link_libraries calls worked
> in versions of CMake prior to 3.21 for some cases, but was not fully
> supported.
One of those cases that do not work is Unix Makefiles generators.
As only Ninja is currently verified to work, this commit will check the
CMake version in use and the generator, and if CMake version <=3.21 is
used with non-Ninja generator then an error is raised informing user
to either use Ninja generator or update CMake.
As the Ninja generator has been confirmed to work as expected, then that
generator is accepted with CMake 3.20 and older.

A "Linker script" choice group has been added to the linker options
menu.
The existing HAVE_CUSTOM_LINKER_SCRIPT config has been relocated inside
the linker script menu.
Two new entries has been created:
- LD template, for using the old ld template files together with the C
pre-processor to create the final linker script.
- CMake linker generator, used for ARMClang / armlink toolchain.
The CMake linker generator is also supported for LD linker scripts
for the ARM architecture.
In CMake, the file cmake/linker/ld/target.cmake has been updated to
support the CMake LD linker generator.

Adding intial version of linker_script_common.cmake.
This script parses memory regions, groups, sections, settings, and
symbols defined in the Zephyr CMake build system.
The linker script creates objects for each type above and groups
sections, symbols, and groups together based on their configuration.
This creates a hierarchy which the `<linker>_script.cmake`
implementations can then use during linker script generation.
linker_script_common.cmake also provides stubs for <type>_to_string()
functions which are used when generating the output script.
Each specific `<linker>_script.cmake` must implement those to_string()
functions to create the final linker script.
