Expose `[data-drag-preview]` on dragged preview div

### Provide a general summary of the feature here

I would like to implement a UX where the dragged item a GridList is slightly tilted, but all other styles remain, like so:


### 🤔 Expected Behavior?


### 😯 Current Behavior

Currently, there is no way to add purely additive styles. The only way to customize the appearance of the drag preview is by providing your own `renderDragPreview`.

The downside of this, is that relative styles are lost. For example, restoring the width of the `div` is difficult if its based on the size of its container.

### 💁 Possible Solution

Add a `data-drag-preview` attribute on the default drag preview, so that additional styles could be added to it easily.

Locate the GridList default drag-preview implementation and compare it with the renderDragPreview path. Add the requested data-drag-preview hook to the default preview without replacing its existing sizing behavior, then verify that consumers can apply additive styles while dragging.
