[PATCH 1/3] kasan: consistently disable debugging features

[Andrey Konovalov]

KASAN is incompatible with some kernel debugging/tracing features.
There's been multiple patches that disable those feature for some of
KASAN files one by one. Instead of prolonging that, disable these
features for all KASAN files at once.
