redhat/configs: Enable CONFIG_KASAN_INLINE for RT debug kernel
Enabling CONFIG_KASAN_INLINE has the effect of improving RT debug kernel
performance by up to 2x depending on the workloads and architecture. The
downside is the increase in the kernel text size by up to 50%. This may
make the RT debug kernel harder to run on systems with limited memory.
So it is a trade off.
Since RT debug kernel performance is becoming a problem, just move
the rt/debug CONFIG_KASAN_{INLINE,OUTLINE} files to automotive/debug
so that RT debug kernel will now use CONFIG_KASAN_INLINE while the
automative debug kernel will continue to use CONFIG_KASAN_OUTLINE as
the automative systems are likely to have less memory.
