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.

Show that trampolining thread self-aborts to the idle thread
works and that we have sufficiently set the idle stack size
for this, PM hooks, and dynamic kernel object cleanup.

Possibly copypasta, or improvements to the test, either way
this test doesn't use that much RAM especially if memory
protection isn't active.

There are predictable relationships between the actual size
of a stack object, the return value of K_*_STACK_SIZEOF() macros,
and the original size passed in when the stack was declared.

These stacks are appropriate for threads that run purely in
supervisor mode, and also as stacks for interrupt and exception
handling.
Two new arch defines are introduced:
- ARCH_KERNEL_STACK_GUARD_SIZE
- ARCH_KERNEL_STACK_OBJ_ALIGN
New public declaration macros:
- K_KERNEL_STACK_RESERVED
- K_KERNEL_STACK_EXTERN
- K_KERNEL_STACK_DEFINE
- K_KERNEL_STACK_ARRAY_DEFINE
- K_KERNEL_STACK_MEMBER
- K_KERNEL_STACK_SIZEOF
If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_*
are equivalent.
Separately generated privilege elevation stacks are now declared
like kernel stacks, removing the need for K_PRIVILEGE_STACK_ALIGN.

Currently for informational purposes, although we do check that
the carveout is smaller than the stack_size.

thread->stack_info is now much more well maintained. Make these
tests that validate that user mode has no access just outside
the bounds of it, instead of the entire object.
