kasan: clean up feature flags for HW_TAGS mode
- Untie kasan_init_hw_tags() code from the default values of
kasan_arg_mode and kasan_arg_stacktrace.
- Move static_branch_enable(&kasan_flag_enabled) to the end of
kasan_init_hw_tags_cpu().
- Remove excessive comments in kasan_arg_mode switch.
- Add new comments.
