Move the syscall_handler.h header, used internally only to a dedicated
internal folder that should not be used outside of Zephyr.

Twister now supports using YAML lists for all fields that were written
as space-separated lists. Used twister_to_list.py script. Some artifacts
on string length are due to how ruamel dumps content.

Change for loops of the form:
for (i = 0; i < CONFIG_MP_NUM_CPUS; i++)
...
to
unsigned int num_cpus = arch_num_cpus();
for (i = 0; i < num_cpus; i++)
...
We do the call outside of the for loop so that it only happens once,
rather than on every iteration.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

A separate privileged stack is used when CONFIG_GEN_PRIV_STACKS=y. The
main stack guard area is no longer needed and can be made available to
the application upon transitioning to user mode. And that's actually
required if we want a naturally aligned power-of-two buffer to let the
PMP map a NAPOT entry on it which is the whole point of having this
CONFIG_PMP_POWER_OF_TWO_ALIGNMENT option in the first place.

Fix the broken logic in the kernel/thread_stack test
The modified test should do direct read & write from estimated stack
pointer to highest address in the stack buffer.
Previously this test was start from lowest address in the stack
which would trigger exception of hardware stack checking scheme
violation on ARC boards and other targets with hardware stack
overflow detection.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Thread stack memory on coherence platforms needs to be linked into a
special section (so it can be cached).
Also, the test_idle_stack case just can't work with coherence. It's
measuring the CPU's idle stack's unused data, which was initialized at
boot from CPU0, and not necessarily the CPU on which the test is
running. In practice on intel_adsp_cavs15, our CPU has stale zeroes
in the cache for its unused stack area (presumably from a firmware
memory clear at boot or something?). Making this work would require a
cache invalidate on all CPUs at boot time before the idle threads
start, we can't do it here in the test because we don't know where the
idle stack pointer is.
Too much work for an esoteric stack size test, basically. Just
disable on these platforms.

This test was written to use a TINY system heap (64 bytes) from which
it has to allocate on behalf of a userspace process. The change in
convention from mem_pool (where the byte count now includes metadata
overhead) means it runs out of space. Bump to 192 bytes. Still tiny.
