Meta: Ensure filters are backwards compatible for pre-4.6 style meta registration.

When using `register_meta()` with the function signature from 4.5 and earlier, the `auth_{$type}_meta_{$key}` and `sanitize_{$type}_meta_{$key}` filters are used. Any calls to `register_meta()` expecting this behavior should continue to work. The new filters, which take advantage of object subtypes, should not be added unless the proper `$args` array is passed.

See #35658.
