Fixes: #25215 This commit introduces the possibility of defining ROOTs in a Zephyr module and have it automatically appended to list of other ROOTs. Supported with this commit: - BOARD_ROOT - SOC_ROOT - DTS_ROOT - ARCH_ROOT In order to support this in Zephyr module files, the detection of west has been moved to dedicated west.cmake file and included immediately after python.cmake. Also the inclusion of zephyr_modules.cmake has moved before first use of BOARD_ROOT. Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>
