cmake: define and create KCONFIG_BINARY_DIR if it doesn't exists

Browse source 
The Zephyr CMake module kconfig.cmake will create files inside
KCONFIG_BINARY_DIR.

In a default Zephyr build setup, this directory is created by Zephyr
CMake module zephyr_module.cmake. But Zephyr CMake modules are modular
and thus it must be possible to use kconfig module without
zephyr_module.

Thus kconfig.cmake must set and create KCONFIG_BINARY_DIR if it does not
already exists.
