Tony Wickham 6a71a5bd77 Add undo snackbar for deleting items
- Add methods to ModelWriter to prepareForUndoDelete, then
  enqueueDeleteRunnable, followed by commitDelete or abortDelete.
- Add Snackbar floating view
- Show Undo snackbar when dropping or flinging to delete target; if the
  undo action is clicked, we abort the delete, otherwise we commit it.

Sunny Goyal 1797af41d1 Cleaning up drag state management.
When the drag is started, the UI automatically goes into spring loaded mode. On a successful
drop, it is the responsibility of the {@link DropTarget} to exit out of the spring loaded
mode. If the drop was cancelled for some reason, the UI will automatically exit out of this mode.

Tony Wickham 10236d6ac7 Update pre-drag lifecycle for apps with shortcuts.
- 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).

Tony Wickham 6e74e899d3 Refactor shortcuts drag and drop.
- 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.
