rustdoc: Add missing item types to page titles

Most pages include the item type in the title such as "Struct std::vec::Vec". However it is missing from the pages for foreign functions, type definitions, macros, statics and constants. This adds them so for example, instead of a title of "std::u32::MAX" it is "Constant std::u32::MAX" to match the others.
