cmake: kconfig: introduce dedicated unit testing board This commit introduces a dedicated unit testing board. Today, a dedicated Zephyr unit testing scheme exists but is different from how a Zephyr build generally works. For example Kconfig is not possible, resulting on various different hacks to pass Kconfig settings from test cases / testcase.yaml through CMake to the code. Some directly as compile definitions, some as header files with forced inclusion on sources, some with wrapper flags which again results in different define being enabled. There is even cases where a second forced header inclusion undefines previous defines. Unit test often does a manual check for the right boards, like this: > if (NOT BOARD STREQUAL unit_testing) > message(FATAL_ERROR "This project can only be used with...") > endif() Introducing a dedicated unit_testing board under `tests/root` allows us to use Kconfig in unit test samples, and thus proper `prj.conf` and extra Kconfig fragments. Generation of autoconf.h so the overall architecture follows regular Zephyr builds. Proper and uniform error messages when invalid board is selected. The unit_testing board and arch is located under: `subsys/testsuite` so that it is only available when find_package(Zephyr COMPONENTS unittest) is used, and not available for regular Zephyr builds. Kconfig generates autoconf.h which is applied as compile flag to test binary which means that kconfig defines placed in ztest.h can now be removed.

The unit_testing architecture identifies itself as X86 for basic
ztest and kernel support.

drivers: Console: Move all posix arch boards to same driver All posix arch boards are required to provide the same tracing/print API. So, instead of having a different driver for native_posix and the bsim boards, let's have a common one which uses this API. This in turn results in the printk strings being printed in the same underlaying backend as before with individual drivers. A part from this, the native_posix console driver was a full backend for the now long gone Zephyr console shell (named legacy_shell from 527256501f01f5a910be6e3e063ed100775ba798 until it was retired in fd0b7f77677a708d031160547c68132939be770f). The whole input handling in this driver was dead code (since 140a8d0c8aeb27034f86938622e5accd16d5e5ad) Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>
