In particular this inlines the accessKeyAction, removes isInteractiveContent() which was for special casing certain elements in event dispatch, and removes eventParameterName() which was only needed for inline event handlers. I also moved Node::commonAncestor into NodeRenderingTraversal, the only callers of it passed NodeRenderingTraversal::parent as the second argument, it didn't make sense to have this generic thing.
