kasan, arm64: only init shadow for software modes
This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
Hardware tag-based KASAN won't be using shadow memory. Only initialize it
when one of the software KASAN modes are enabled.
No functional changes for software modes.
