This moves the k_* memory management functions from sys/ into
kernel/ includes, as there are kernel public APIs. The z_*
functions are further separated into the kernel internal
header directory.
Also made a quick change to doxygen to group sys_mem_* into
the OS Memory Management group so they will appear in doc.

These tests cannot be run in this architecture as it does not
support userspace.
Today they are filtered by kconfig, which works but spends
time running cmake.
As native_posix is a default test platform it is better
to filter it alltogether by arch, which saves quite a lot

As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

For some kernel tests, faults and exceptions are expected.
They are caught and the test would continue if the reasons
for faults are as expected. However, when the unexpected
reasons are encountered, the code simply prints a message
and calls k_fatal_halt(). When running under twister,
these messages are not the expected failed messages so
twister will spin till timeout although the execution
has already been halted. This adds another printk() before
halt to signal twister that the test has failed and bails
early.

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.

The irq_lock() API is a legacy API not to be used for synchronization
by new code, and in any case is only being used in cargo-cult fashion
here. These test cases all do synchronous exceptions, there's
literally nothing to synchronize against.
(And in this case they're exposing a legacy wart. On platforms where:
1. SMP=y, which causes irq_lock() to be implemented as a somewhat
complicated global lock
2. No ARCH_EXCEPT() macro is defined, which causes the kernel to
use a fallback that simply aborts the current thread.
...this test will then abort a thread holding the lock, which will
cause it to be orphaned (if it weren't a legacy API, the kernel
should probably attempt to clean it up in k_thread_abort(), but it
is, and it doesn't), so the next attempt to lock it will hang.
And it's even worse, because this test builds with SMP=y and
MP_NUM_CPUS=1, so the hand will happen with interrupts masked on a
system with only one CPU, and everything will lock up solid.)

This test takes an interrupt lock and tries to call z_swap_unlocked()
while holding it. That's not legal (in the general case it means
you're breaking a caller's lock!), though in this particular case it
was safe because we'll never return to this.
Regardless, there is a natural z_swap_irqlock() that releases the lock
atomically. Use that.

This platform has a tiny handful of remaining tests that fail. We
will track them as issues, but let's exclude them from integration
testing to allow full runs to complete. Often a hung device in one
test will break an entire twister run.
Tests with known (and tracked) failures:
samples/application_development/external_lib
samples/posix/eventfd
samples/userspace/hello_world_user
tests/kernel/fatal/message_capture
tests/net/socket/socketpair
tests/portability/cmsis_rtos_v2
These tests never fail in isolated testing, but are reliable timeouts
when run in sequence in a big twister run. It's possible that the bug
here may be in twister or the flash/serial scripts:
tests/crypto/tinycrypt
tests/subsys/logging/log_immediate

The "sentinel" variant of this test runs the same code, but enables
the stack sentinel feature. Inexplicably, it's also disabling
TICKLESS_KERNEL, forcing a timer interrupt at every tick boundary.
That doesn't seem to be required for any test functionality I can see.
And worse, by changing that setting without adjusting the tick rate,
it runs afoul of more modern platforms which were designed with
tickless operation in mind. Specifically, the intel_adsp platforms
have a default tick rate of 50 kHz, which is just too fast for
reasonable operation. It leaves almost no time available for
application code and something falls behind and fails.
Just remove it.
