GenericTransformUpdateDetails class

GenericTransformUpdateDetails genericizes all used input events into a single class. This allows us to use the same logic for all input events.

Not all properties are used for all input events. For example, the PointerMoveEvent does not have a scale property, so it will always be 1.0.

You can use kind to determine the input type.
