This changes both k_mem_domain_add_partition() and
k_mem_domain_remove_partition() to return errors instead of
asserting when errors are encountered. This gives the application
chance to recover.
The arch_mem_domain_parition_add()/_remove() will be modified
later together with all the other arch_mem_domain_*() changes
since the architecture code for partition addition and removal
functions usually cannot be separately changed.

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

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
tests/subsys/logging/log_output

Use the core k_heap API pervasively within our tree instead of the
z_mem_pool wrapper that provided compatibility with the older mempool
implementation.
Almost all of this is straightforward swapping of one alloc/free call
for another. In a few cases where code was holding onto an old-style
"mem_block" a local compatibility struct with a single field has been
swapped in to keep the invasiveness of the changes down.
Note that not all the relevant changes in this patch have in-tree test
coverage, though I validated that it all builds.

This code used a sys_mem_pool directly. Use a new-style heap instead
to do the same thing.
(Note that the usage is a little specious -- it allocates from the
heap but doesn't appear to fill or check any data therein, just that
the heap memory can be copied from the two memory domains. It's
unclear exactly what this is trying to demonstrate and we might want
to improve the sample to do something less trivial.)

This provides a better error message when building with CMake and

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

This test uses bare variables to synchronize state between threads,
but had forgotten volatile qualifiers on all the data. So the
compiler was free to reorder and make assumptions that aren't valid
when the values are being written from other CPUs.
Single-cpu operation was fine because the code would always hit an
external function call like k_sleep() that would force it to re-read
from memory every time there was a context switch (timeslicing isn't
enabled on this test and the threads are cooperative), but on SMP the
volatiles can change at any time and we could see spurious state
mixups and hangs.

There was some unlocked initialization code in the "enc" thread that
would race with the "pt" and "ct" threads if another CPU was available
to run them (it was safe on UP because "enc" entered the queue first
and was cooperative, the others wouldn't run until it blocked).
Move it to main() and remove the enc_state guard variable which is no
longer doing anything.

- Multiple logical applications, each with their own memory
domain
- Creation of a sys_mem_pool and assignment to a memory
partition
- Use of APIs like k_queue_alloc_append() which require
thread resource pools to be configured
- Management of permissions for kernel objects and drivers
- Show how application-specific system calls are defined
- Show IPC between ISR and application (using k_msgq) and
application-to-application IPC (using k_queue)
