  [GTK4] NativeWebWheelEvent crashes on wheel event tests

Reviewed by Michael Catanzaro.

The GdkEvent API in GTK4 won't play ball when given a NULL event.
When synthesizing wheel events we might pass a NULL event to the
event factory, so make sure that the methods that call GDK API
on it are NULL-safe.
