Description

When SlateApplication is routing a pointer up event, it should check bIsDragDropping and call the widget's OnDrop function. Currently, we check for touch events and call OnTouchEnded without checking if we're dragging.

Steps to Reproduce
  1. Create a widget that implements NativeOnDrop
  2. Create a widget that implements NativeOnMouseButtonDown and NativeOnDragDetected.
  3. Using a touch device, drag your draggable widget onto your drop zone widget
  4. OnDrop will not be called
