This introduces KCONFIG_BOARD_CONFIG and KCONFIG_CPU_CONFIG variable for boards and CPUs (including common directories) to add default configuration files to be merged. The current approach, as it uses Makefile.features, would include boards first, not allowing them to override CPU configurations.

Contribution description
This introduces
KCONFIG_BOARD_CONFIGandKCONFIG_CPU_CONFIGvariable for boards and CPUs (including common directories) to add default configuration files to be merged. The current approach, as it usesMakefile.features, would include boards first, not allowing them to override CPU configurations.Documentation on this is added as well.
Testing procedure
stm32f769i-disco, which has configuration files from different sources (board, stm32, cortexm_common), now the order is the correct: 1st the arch, 2nd the cpu, 3rd the board. This can be seen by printingMERGE_SOURCESfrommakefiles/kconfig.mkand building withTEST_KCONFIG=1.Issues/PRs references
