windowPreview: Replace the click action with a click and long press gesture

In the porting, temporarily stop integrating the WindowPreview gestures with
DnD, this used to be done through addClickAction() but DnD will change to
using gestures in later commits, making its porting moot. This integration
will be restored later on.
