Adds support for pointer signals, in a way that will support both discrete events (e.g., scroll wheels, flutter/flutter#22762) and continuous gestures (e.g., trackpad scroll, flutter/flutter#21953). Also exposes these new event options to the embedder. Does not include code to send the new events from the platform shells.
