Mark all k_mem_pool APIs deprecated for future code. Remaining

re-enabling this test was premature, it still crashes very often
due to two known issues affecting x86 64-bit. Filter out for
every 64-bit x86 platform until those bugs are solved, which

This provides a better error message when building with CMake and
forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package
registry. See parent commit for more details (split from parent for
better readability).

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.

We try to demonstrate some concepts for user mode:
- 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)

While trying out the hello_world sample built for QEMU, I was expecting
the sample app to exit and I'd return to a command prompt. Nope. You

this added step after running the sample app.

This was never a long-term solution, more of a gross hack
to get test cases working until we could figure out a good
end-to-end solution for memory domains that generated

to remove it, delete this feature.
To date all userspace APIs have been tagged as 'experimental'
which sidesteps deprecation policies.
