The xtensa-asm2 work included a patch that added nano_internal.h
includes in lots of places that needed to have _Swap defined, because
it had to break a cycle and this no longer got pulled in from the arch
headers.
Unfortunately those new includes created new and more amusing cycles
elsewhere which led to breakage on other platforms.
Break out the _Swap definition (only) into a separate header and use
that instead. Cleaner. Seems not to have any more hidden gotchas.

_Swap() is defined in nano_internal.h. Everything calls _Swap().
Pretty much nothing that called _Swap() included nano_internal.h,
expecting it to be picked up automatically through other headers (as
it happened, from the kernel arch-specific include file). A new
_Swap() is going to need some other symbols in the inline definition,
so I needed to break that cycle. Now nothing sees _Swap() defined
anymore. Put nano_internal.h everywhere it's needed.
Our kernel includes remain a big awful yucky mess. This makes things
more correct but no less ugly. Needs cleanup.

Split the search into two loops: in the common scenario, where device
names are stored in ROM (and are referenced by the user with CONFIG_*
macros), only cheap pointer comparisons will be performed.
Reserve string comparisons for a fallback second pass.

The read/write_kernel_stack tests are confusingly named and incorrectly
implemented for ARM; they are intended to test that user mode threads
cannot read or write their privileged stacks. The privileged stacks
on ARM are not relative to the user stack, and thus their location
cannot be computed from the user stack. To find the privileged stack on
ARM, we have to use _k_priv_stack_find(), which we do during setup
in test_main() rather than from the usermode thread itself. Accessing
thread_stack directly from the test function requires making it
non-static in ztest, so we also give it a ztest_ prefix to avoid
collisions with other test programs. Rename the test functions and
global pointer variable to more accurately reflect their purpose.

This PR includes the required changes in order to support
conditional compilation for Armv8-M architecture. Two

- the Armv8-M Mainline (backwards compatible with ARMv7-M).

Check the fault reason against the expected value.
This is presently architecture-specific, and possibly
reflects a bug on ARM (all faults end up with reason 0,
even though ARM does define a separate value for Oops).

Tests system call memory buffer read/write validation using the
k_pipe_get() and k_pipe_put() calls from a userspace thread.
Specifically, this tests _SYSCALL_MEMORY_READ/WRITE checks
by the system call handler by attempting to read/write to a
kernel object.
write_kobject_user_pipe() attempts to write over a kernel object
by using the kernel object's location as the buffer to place
the data read from the pipe.
read_kobject_user_pipe() attempts to read a kernel object by using
the kernel object's location as the location of data to be placed
into the pipe.
Tested on qemu_x86 and frdm_k64, passes on both.

Added three tests for kernel objects focusing on 1) revoking
access to a k_object that the thread does not have
permissions to access, 2) accessing a k_object after
permissions to access it were revoked, and 3) trying to
revoke access to a k_object from a parent thread by a
child thread. Additionally, added a test for
k_thread_user_mode_enter().
revoke_noperms_object() tests by calling
k_object_access_revoke() on a semaphore (kernel object) that it
does not have access to (ksem).
access_after_revoke() tests ability to access a semaphore after
access has been revoked by itself.
revoke_other_thread() tests whether a thread can revoke access
for an object for which it has permissions from a thread for
which it does not have permissions.
user_mode_enter() tests whether k_thread_user_mode_enter()
truly enters user mode.
Tested on qemu_x86 and frdm_k64 with pr-4974 applied, passes
on qemu_x86 but requires small fix for ARM (will submit
separately).

Running this testcase on qemu without userspace enabled it
crashes. The testcase was modifing page table information

different location.

Make it possible to run in other posix boards.
By default, if the POSIX board does not define the TICK_IRQ
just run without that part of the test, printing a note.
The place where other POSIX boards should define it, is also
clear, and should be easy to keep those lines free from merge
conflicts in the future.

The following 3 testcases are blacklisted for the POSIX
arch / simple_process BOARD:
* tests/drivers/ipm : won't compile due to missing
__stdout_hook_install() [part of minimal libc]
(POSIX arch uses the native libc)
* tests/kernel/mem_protect/stackprot : will crash
"natively" when trying to corrupt the stack and therefore
will fail the testcase. The current understanding is that
the POSIX arch should let the native OS handle faults,
so they can be debugged with the native tools.
* samples/cpp_synchronization : it is not possible
to build cpp code yet on top of the posix arch
