Avoid recreating the SnapshotStateList for edit mode at every changes

This helps reduce jank.
As a result, two bugs were uncovered:
- The resizing anchors would be updated with the wrong size values. Using the LazyGridState to calculate the bounds fixes this issue.
- The DragAndDrop API would _sometimes_ stop the tile content from initially composing when a tile is resized rapidly. Applying the DragAndDrop modifier after the first frame fixes this
