added accessibilityIgnoresInvertColors to module.exports in ViewPropTypes

Summary:
Previously, I exposed the "accessibilityIgnoresInvertColors" API on iOS to react native views.

In this diff, I added this property to the `module.exports` in `ViewPropTypes` so that the property can be accessed by other files.
