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).
