Style/Documentation with only macros

[marcandre]

I'd like Style/Documentation to accept the following:

module RuboCop
  module AST
    # Responsible for compatibility with main gem
    # @api private
    module RuboCopCompatibility
      # ...
    end

    extend RuboCopCompatibility  # => This triggers Style/Documentation: Missing top-level module documentation comment
  end
end

I think that (at least) macro calls like extend should not trigger it.
