cmake: support hw model v2 in arch/Kconfig tree

This commit introduces support for Zephyr hw model v2 in the arch
Kconfig tree.

The hw model v2 requires Kconfig trees to be self-contained, meaning
that the have no Kconfig references outside the tree itself.

For hw model v2, the architecture of a board / SoC is not known until
the Kconfig tree and config file has been parsed.
There provide a new arch/Kconfig.v2 file to support loading of all arch
Kconfigs. Hw model v1 is now placed in arch/Kconfig.v1 and includes
only the arch Kconfig files determined by the arch of the board.
