mm/kasan/kasan.h provides a number of empty defines for a few arch-specific tagging-related routines, in case the architecture code didn't define them. The original idea was to simplify integration in case another architecture starts supporting memory tagging. However, right now, if any of those routines are not provided by an architecture, Hardware Tag-Based KASAN won't work. Drop the empty defines, as it would be better to get compiler errors rather than runtime crashes when adding support for a new architecture. Also drop empty hw_enable_tagging_sync/async/asymm defines for !CONFIG_KASAN_HW_TAGS case, as those are only used in mm/kasan/hw_tags.c.
