Make (Async)GeneratorType type parameters consistent with (Async)Generator type parameters (#14789)

Browse Source 
Currently `Generator` is generic over three type variables that have defaults, but `GeneratorType` is generic over three type variables that do not have defaults. It seems like it probably makes more sense for them to be consistent? The vast majority of real-world `Generator`s are instances of `GeneratorType`
