While the launcher is loading, the drag view is displayed with a gray tint.
The drag is started, as soon as the workspace is unlocked

- First of all, deferred drag has been renamed to pre-drag
to avoid confusion with the existing deferred end drag.
- For normal drags, the cycle is still startDrag -->
onDragStart --> onDrop --> onDropComplete --> onDragEnd.
- Pre-drags have two additional callbacks: onPreDragStart
and onPreDragEnd. onPreDragStart is called between
startDrag and onDragStart, and onPreDragEnd is called
at the same time as onDragStart or onDragEnd.
- If the pre-drag has not transitioned to a full drag before
onDragEnd, onDragStart and onDropComplete are skipped
(onDrop is still called to allow the DragView to animate).

- Instead of creating our own drag view within the container, and
handling logic to determine when to start a real drag, we start
the drag immediately and just defer onDragStart().
- To determine when the deferred drag should start, we add a
DeferDragCondition to DragOptions. The default DeferDragCondition
never defers a drag, but is overridden for apps with shortcuts
to defer until the icon is dragged a given distance.
- Because the drag is handled in DragController, including checking
when to start the deferred drag, DeepShortcutsContainer no longer
needs to handle touch events and ShortcutsContainerListener has
been removed.
This change has several immediate benefits:
- The code is much cleaner, because it allows touch handling to be
done by the DragController through the normal drag flow, without
recreating logic in ShortcutsContainerListener/DeepShortcutContainer.
- The janky second haptic feedback has been removed (now it vibrates
when you long press, like everywhere else, but not again when the
shortcuts close after dragging a distance).
- Drops are animated, instead of just popping the icon back into place.

1) Adding DragOptions to easily extend drap functionality
2) Changing onDragStarted signature to send more information
3) Updating states for dropTargetButton based on drag event directly
4) Removing folder item based on onDragStarted and not startDrag
