Fix accessibilityState serialization for props diffing of View component (#51420)

Summary:

The checked and unchecked state of the accessibility state property has to be serialized as `{ "checked": true }` and `{"checked": false}`.

This diff updates the serialization of the `accessibilityState` prop for the prop diffing on the View component.

This fixes the e2e test selectors for radio buttons.
