Enable Layout/EmptyLinesAroundAccessModifier cop

We sometimes say "✂️ newline after `private`" in a code review (e.g.
rails#18546 (comment),
rails#34832 (comment)).

Now `Layout/EmptyLinesAroundAccessModifier` cop have new enforced style
`EnforcedStyle: only_before` (rubocop/rubocop#7059).

That cop and enforced style will reduce the our code review cost.
