This commit removes explicit `CONFIG_NEWLIB_LIBC_NANO=n` overrides
because the newlib nano variant is no longer enabled by default when
it is available.

The newlib full malloc implementation (i.e. non-nano) requests a
relatively large 4096-byte memory chunk through `_sbrk`, which exceeds
the configured 512-byte heap size.
This commit changes `CONFIG_NEWLIB_LIBC_ALIGNED_HEAP_SIZE` from 512 to
8192 in order to increase the size of the heap memory used by the
newlib malloc function.
For more details, refer to the issue #21167.

NEWLIB_LIBC_NANO defaults to y when building with a toolchain that
supports nano.specs and this was causing the libraries.libc.newlib
test to link with the newlib nano variant (libc_nano.a) when it should
be linking with the normal newlib (libc.a).
By setting CONFIG_NEWLIB_LIBC_NANO=n in prj_newlib.conf, we make sure
that the libraries.libc.newlib test links with the normal newlib.
For more details, refer to the issue #21167.

This test uses ztest, there is no need to set this and it
was breaking builds with CONFIG_COVERAGE=y

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)

* 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.

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.
