Ziqi Chen ca01290d8e changed prop name currentViewStates to AccessibilityStates on iOS (3/3)
Summary:
Context:
After discussing with yungsters, `currentViewStates` is a very ambiguous name for a prop, especially because there are only two possible values. From a developer's perspective, it makes more sense to just call them `accessibilityStates` because the main use for them is to add states to Talkback and Voiceover.
Also, the actual implementation of what we're changing under the hood in Native Code is abstracted away from developers using React Native, so as long as behavior is as they would expect, it makes more sense to change the name into a clear one.

Changes in this Diff:
Renamed the view property exposed to native iOS code from `currentViewStates`  to `accessibilityStates`
Also deleted setting the userInteractionEnabled view property, because we want to keep it as just an accessibility property.
