kbuild: Add config fragment merge functionality So far this function was only used locally in powerpc, some other architectures might benefit from it. Move it into scripts/Makefile.defconf.

kbuild: Provide a version of merge_into_defconfig without override warnings While warning on overridden Kconfig options is a good default for merging config fragements sometimes that is our explicit intent and the warnings are unhelpful, add a new merge_into_defconfig_override which does the merge but with warnings suppressed. Since merge_into_defconfig accepts any number of fragments it is difficult to allow it to accept the flag.
