The kasan-enabled.h header relies on static keys, so make sure
to include the header to avoid compilation errors (with JUMP_LABEL=n).
It fixes the following:
./include/linux/kasan-enabled.h:9:1: warning: data definition has no type or storage class
9 | DECLARE_STATIC_KEY_FALSE(kasan_flag_enabled);
| ^~~~~~~~~~~~~~~~~~~~~~~~
error: type defaults to 'int' in declaration of 'DECLARE_STATIC_KEY_FALSE' [-Werror=implicit-int]
Fixes: f9b5e46f40 ("kasan: split kasan_*enabled() functions into a separate header")

In an upcoming commit we are going to need to call
kasan_hw_tags_enabled() from arch/arm64/include/asm/mte.h. This
would create a circular dependency between headers if KASAN_GENERIC
or KASAN_SW_TAGS is enabled: linux/kasan.h -> linux/pgtable.h ->
asm/pgtable.h -> asm/mte.h -> linux/kasan.h. Break the cycle
by introducing a new header linux/kasan-enabled.h with the
kasan_*enabled() functions that can be included from asm/mte.h.
