Move the syscall_handler.h header, used internally only to a dedicated
internal folder that should not be used outside of Zephyr.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
All in-tree uses of the function have been adapted.
Fixes#61888.

portability.posix.common.arcmwdtlib test fails with ARCMWDT libc.
This path fixes the test.
STDIN_FILENO and others macroses are used in libc-hooks.c only. So they
defined localy.

In order to bring consistency in-tree, migrate all lib code to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to zephyrproject-rtos#45388 for more details.

This commit removes the `z_` prefix from the stdio syscall functions
(`z_zephyr_write_stdout` and `z_zephyr_read_stdin`) since it is
redundant and does not align with the convention used by the equivalent
minimal libc syscall functions (e.g. `zephyr_fputc` and
`zephyr_fwrite`).

The newlib `write()` and `read()` functions must call the
`z_zephyr_write_stdout()` and `z_zephyr_read_stdin()` syscall functions
in order to function properly in a user mode context.
The existing incorrect implementation was copied off the newlib hooks
implementation, which was corrected in the previous commit.

ARC MWDT libraries require to implement locking interface
otherwise not all of functionality is guarantee to be
thread-safe.
So, let's implement locking interface.

Default weak _exit implementation from ARC MWDT libs
calls _exit_halt from startup libs. As we are going to
get rid of startup libs usage let's implement _exit
stub.

ARC MWDT toolchain misses stdout hooks implementation and
itimerspec structure in timespec header. Let's add them in
arcmwdt compatibility layer.
The implementation was inspired by libc-hooks.c for NEWLIB.
