Subject: Remove getters for HTML5 related objects from the ResourceContext
 interface. Half of them weren't used by chrome, so they can be hidden from
 chrome. The rest were accessed by chrome, but we don't need every embedder to
 store this data on their ResourceContext implementation. Instead have content
 associate the data itself to simplify the work for embedders.
