TextClassification.text is nullable

Removes the @NonNull requirement on TextClassification.text.
e.g. TextClassifier.NO_OP doesn't classify text and thus returns
TextClassification.EMPTY which doesn't set TextClassification.text.
This is ideal as we need not make copies of this object when NO_OP
was performed.
