util/kconfig: Uprev to Linux 6.6's kconfig

Browse Source 
Upstream reimplemented KCONFIG_STRICT, just calling it KCONFIG_WERROR.
Therefore, adapt our build system and documentation. Upstream is less
strict at this time, but there's a proposed patch that got imported.

TEST=`util/abuild/abuild -C` output (config.h and
config.build) remains the same. Also, the failure type fixed in
https://review.coreboot.org/c/coreboot/+/11272 can be detected,
which I tested by manually breaking our Kconfig in a similar way.
