Async mode support has already been implemented in commite80a76aa1a("kasan, arm64: tests supports for HW_TAGS async mode") but then got accidentally broken in commit99734b535d("kasan: detect false-positives in tests"). Restore the changes removed by the latter patch and adapt them for asymm mode: add a sync_fault flag to kunit_kasan_expectation that only get set if the MTE fault was synchronous, and reenable MTE on such faults in tests. Also rename kunit_kasan_expectation to kunit_kasan_status and move its definition to mm/kasan/kasan.h from include/linux/kasan.h, as this structure is only internally used by KASAN. Also put the structure definition under IS_ENABLED(CONFIG_KUNIT).
