[ObjC] Add Swift helpers for
GPBUnknownFields/GPBUnknownField.
`GPBUnknownFields` additions: - Provide `Optional` based apis for the `getFirst*` apis. - Map the `NSFastEnumeration` over as a `Sequence` to support looping over the fields. `GPBUnknownField` addition: - Add an `enum` with associated values to provide a more type-safe way for inspection.
