config: add CC_NO_ARRAY_BOUNDS=y
    
    Mainline commit f0be87c42cbd ("gcc-12: disable '-Warray-bounds' universally
    for now") adds new config option CONFIG_CC_NO_ARRAY_BOUNDS which is only
    present for gcc12 (and not future gcc >= 13). Therefore it is not added
    with dummy gcc which pretends to be gcc20 but it is with Factory gcc12,
    resulting in failed "missing config option" check.
    
    As a quick hack, add CONFIG_CC_NO_ARRAY_BOUNDS=y to all full configs until
    we have a more robust solution (manually added config option won't survive
    a config update with run_oldconfig.sh).
