7b1ee5cf13 tests: CONFIG_TEST_USERSPACE now off by default
Unlike CONFIG_HW_STACK_PROTECTION, which greatly helps
expose stack overflows in test code, activating
userspace without putting threads in user mode is of
very limited value.

Now CONFIG_TEST_USERSPACE is off by default. Any test
which puts threads in user mode will need to set
CONFIG_TEST_USERSPACE.

This should greatly increase sanitycheck build times
as there is non-trivial build time overhead to
enabling this feature. This also allows some tests
which failed the build on RAM-constrained platforms
to compile properly.

tests/drivers/build_all is a special case; it doesn't
put threads in user mode, but we want to ensure all
the syscall handlers compile properly.

Fixes: #15103 (and probably others)

4b4f773484 libc: set up memory partitions
* Newlib now defines a special z_newlib_partition containing
  all globals relevant to newlib. Most of these are in libc.a
  with a heap tracking variable in newlib's hooks.

* Both C libraries now expose a k_mem_partition containing the
  bounds of the malloc heap arena. Threads that want to use
  libc malloc() will need to add this to their memory domain.

* z_newlib_get_heap_bounds has been removed, in favor of the
  memory partition for the heap arena

* ztest now includes the C library partitions in its memory
  domain.

* The mem_alloc test now runs in user mode to prove that this
  all works for both C libraries.

3a82aef5df tests: lib: mem_alloc: Add tests to validate dynamic allocation
Add new test cases to validate dynamic memory allocation
functions such as malloc, calloc, realloc using minimal libc
and newlibc implementation of standard C library.
