This is a pretty fundamental module, and even minimal ports like unix and
zephyr minimal have it enabled. So, enabled it by default at the lowest
feature level.
Most things in the `sys` module are configurable, and off by default, so it
shouldn't add too much to ports that don't already have it enabled (which
is just the minimal port).
Also note that `sys` is still disabled on the bare-arm port, to keep that
ultra minimal. It means we now have bare-arm without `sys` and the minimal
port with `sys`. That will allow different code size comparisons if/when
new `sys` features are added.

This commit adjusts the configuration of the minimal zephyr build to use
MICROPY_CONFIG_ROM_LEVEL_MINIMUM. That's a lot cleaner than explicitly
enabling/disabling options.
Prior to this change the minimal build for qemu_cortex_m3 had size:
Memory region Used Size Region Size %age Used
FLASH: 114436 B 256 KB 43.65%
RAM: 26320 B 64 KB 40.16%
and had the following test results (running using the CI settings, ie
`-d basics float --exclude inf_nan_arith`):
352 tests performed (7092 individual testcases)
352 tests passed
254 tests skipped: ...
With the changes here the qemu_cortex_m3 size is now:
Memory region Used Size Region Size %age Used
FLASH: 99428 B 256 KB 37.93%
RAM: 26312 B 64 KB 40.15%
That's a good decrease of about 15k firmware size. And the test suite
still passes with:
342 tests performed (6776 individual testcases)
341 tests passed
265 tests skipped: ...

Zephyr v3.2.0 deprecated include/zephyr/zephyr.h in favor of
include/zephyr/kernel.h since it only included that header.

Zephyr v3.1.0 moved all public headers to include/zephyr. Updates a few
Zephyr include paths that were missed in
4fd54a4756.

This commit implements the `_thread` module on the zephyr port.
Due to the fact that we are still using a rather old version of Zephyr,
`CONFIG_DYNAMIC_THREAD` is not available and therefore the stack for
threads cannot be allocated dynamically, only at compile time. So for the
time being and for the purpose of this commit, a maximum of 4 Zephyr
threads (besides the main thread) can be created. Once we manage to update
to the latest version of Zephyr this won't be a problem anymore.
Configuration for the nrf52840dk is added as part of this change, because
this board was used to test the threading support.
The Zephyr option `CONFIG_THREAD_CUSTOM_DATA` is used to enable threading
on a per board basis. The `thread.conf` file is added as a convenient way
to enable threading.

This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.
This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
