LibWeb: Implement named property access AOs on Window
These allow accessing embeds, forms, images and objects with a given name attribute, and any element with a given id attribute, as top level properties on the global object. It also allows accessing NavigableContainers by target name as top level properties on the global object. The current implementation feels very expensive. It's likely that these values will need smarter caching in the future.
