added accessibilityStates and accessibilityRole to ReactNativeViewAttributes

Summary:
Previously, I added accessibilityRole and accessibilityStates as View Properties.

In this diff, I added accessibilityRole and accessibilityStates to ReactNativeViewAttributes.UIView, which is used for viewconfig in some components.

The NativeMethodsMixing uses the set view config when invoking `setNativeProps`, and it's used to make those components look like an actual native component class.
