feat: Add visual crop preview widget for ImageCrop node - widget ImageCrop (#7825)

## Summary

Another implementation for image crop node, alternative for
https://github.com/Comfy-Org/ComfyUI_frontend/pull/7014
As discussed with @christian-byrne and @DrJKL we could have single
widget - IMAGECROP with 4 ints and UI preview.

However, this solution requires changing the definition of image crop
node in BE (sent
[here](https://github.com/comfyanonymous/ComfyUI/pull/11594)), which
will break the exsiting workflow, also it would not allow connect
separate int node as input, I am not sure it is a good idea.

So I keep two PRs openned for references
