aura: Enable touch initiated drag and drop.
Touch drag/drop in aura follows the following rules:
1. Initiate drag on long press gesture. Give the user a visual cue by showing
a scaled up drag image.
2. Do not initiate dnd if there is no drag image.
3. If, after initiating a drag, the user lifts up their finger without moving,
cancel the drag and show a context menu (this is implemented using the long tap
gesture).
