[TypedFunctionReferences] Implement call_ref (#3396)

Includes minimal support in various passes. Also includes actual optimization
work in Directize, which was easy to add.

Almost has fuzzer support, but the actual makeCallRef is just a stub so far.

Includes s-parser support for parsing typed function references types.
