rustdoc-search: parse and search with ML-style HOF Option::map, for example, looks like this: option<t>, (t -> u) -> option<u> This syntax searches all of the HOFs in Rust: traits Fn, FnOnce, and FnMut, and bare fn primitives.

rustdoc-search: add search query syntax `Fn(T) -> U` This is implemented, in addition to the ML-style one, because Rust does it. If we don't, we'll never hear the end of it. This commit also refactors some duplicate parts of the parser into a dedicated function.
