Andreas Kling ca08d5a901 LibWeb: Move custom state set invalidation into the helper
CustomStateSet directly selected the style invalidation reason used when
its JS-visible set is modified. Move that mapping into
CSS::Invalidation::CustomElementInvalidator.

This keeps the custom-state container focused on its set contents while
CSS invalidation owns the style work required by :state() selectors.
