Andrey Konovalov 6a63a63ff1 kasan: introduce CONFIG_KASAN_HW_TAGS
This patch adds a configuration option for a new KASAN mode called
hardware tag-based KASAN.  This mode uses the memory tagging approach like
the software tag-based mode, but relies on arm64 Memory Tagging Extension
feature for tag management and access checking.
