coreboot+linux modules: add modules target helpers to edit configs (oldconfig/defconfig)
Most useful to me are: coreboot.modify_and_save_defconfig_in_place coreboot.modify_and_save_oldconfig_in_place linux.modify_and_save_oldconfig_in_place linux.modify_and_save_defconfig_in_place Which permit to take current in tree configs and translate them into other format. This is useful when trying to version bump and build. Also add helpers to save in versioned version to facilitate change tracking: linux.generate_and_save-versioned-oldconfig linux.regenerate_and_save_versioned_defconfig
