config: select KERNEL_WERROR if building with default GCC version
[ during cherry-pick GCC version was changed to default GCC 12 version ] At the moment we have to manually follow the default GCC version also in config/Config-kernel.in. This tends to be forgotten at GCC version bumps (just happened when switching from version 12 to 13). Instead, introduce a hidden Kconfig symbol which implies KERNEL_WERROR in toolchain/gcc/Config.in where it is visible for developers changing the default version. Also remove the explicit default on BUILDBOT to avoid a circular dependency and also because buildbots anyway implicitly always select the default GCC version.

A kernel build should not cause any compiler warnings, and this
enables the '-Werror' (for C) and '-Dwarnings' (for Rust) flags
