Defer ViewModelMetadata processing on error types or missing @AssistedFactory.

This change throws an ErrorTypeException when the assisted factory type is an error type or when the factory class is not yet annotated with @AssistedFactory. This allows the compiler to defer processing to a later round, giving time for the necessary types and annotations to be fully generated.
