Add the ability to correctly determine if a particular field has been validated. 

There are several portions of model validation that attempt to avoid
revalidating if a field has been validated. However the behavior of
ModelStateDictionary makes it difficult to distinguish between an
unvalidated field and a field without validation errors. This change
resolves this issue by letting the caller distinguish between the two
cases.
