kPointerUndefined is unused in Blink, and WebTouchPoint::State has a
"stationary" state that we need here. Other than these two, all states are 1:1
with event types, right?

From that perspective, we only need to store a Boolean here for the stationary
state.

I did the same idea in the new CL. But I don't add a new enum anymore. The
boolean is called stale_ and is stored in TouchEventManager.
