chore: Fix ODFV decorator

[felixwang9817]

What this PR does / why we need it: #2514 switched from using Feature to Field for declaring types of features in FeatureViews and OnDemandFeatureViews. It left a TODO to make the same change for the ODFV decorator; this PR completes that TODO. It also ensures that a previous change, #2442, does not break users using the ODFV decorator. It also enforces the usage of kwargs for the ODFV decorator.
