Summary:
Pull Request resolved: facebook#37537

Changelog: [Internal] [Changed] - W3CPointerEvents: add missing attributes to pointer events

The [PointerEvent interface](https://www.w3.org/TR/pointerevents/#pointerevent-interface) includes some additional properties which we weren't including in the events we dispatched.

This diff adds them (set to default values):
- twist
- tangentialPressure

In the future, we can try to set reasonable values for these properties based on the underlying native events.
