RuboCop::MagicComment#frozen_string_literal?

Does the magic comment enable the frozen string literal feature.

Test whether the frozen string literal value is `true`. Cannot
just return `frozen_string_literal` since an invalid magic comment
like `# frozen_string_literal: yes` is possible and the truthy value
`'yes'` does not actually enable the feature
