Stop generating unnecessary reference to field type

Browse Source 
This commit updates the generator to stop specifying a field type when
reflection is necessary, or when a reference to a field should be
retrieved as its name alone suffices.

This could trigger package protected issues if the field type is not
public.

See gh-28047
