[PATCH 2/5] kasan, arm64: rename tagging-related routines

[andrey.konovalov@linux.dev]

From: Andrey Konovalov <andreyknvl@google.com>

Rename arch_enable_tagging_sync/async/asymm to
arch_enable_tag_checks_sync/async/asymm, as the new name better reflects
their function.

Also rename kasan_enable_tagging to kasan_enable_hw_tags for the same
reason.
