This adds a new class `ElementReferencePseudoElement` which forwards any accesses to the referenced element for "element-reference" pseudo elements. This allows us to, for instance: - Access the underlying `ComputedProperties` in getComputedStyle, which includes inline style. - Store and access `CustomPropertyData` - Access the layout node for "resolved value" computation - Apply animations from `update_animated_style_if_needed` We register these with the originating element when calling `set_associated_shadow_host_pseudo_element`, this requires us to append the element to the tree beforehand since we need to be able to get the shadow host.
