The DOM spec defines what it means for an element to be an "editing host", and the Editing spec does the same for the "editable" concept. Replace our `Node::is_editable()` implementation with these spec-compliant algorithms. An editing host is an element that has the properties to make its contents effectively editable. Editable elements are descendants of an editing host. Concepts like the inheritable contenteditable attribute are propagated through the editable algorithm.
