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.
