unittest: update unittest to hwmv2

Follow-up: fe25709a9c twister: add unit_testing soc and board

Moving the soc.yml and board.yml to subsys/testsuite tree.
Introduce subsys/testsuite/arch/archs.yml with unit_testing arch.

Update the Zephyr CMake module unittest.cmake to include HWMv2 and
reorder includes to follow same order as zephyr_default.cmake.
