RFR: 8344204: IGV: Button to enable/disable cutting of long edges

[Tobias Holenstein]

Currently IGV layout cuts edges that are longer than 10 layers. Add an option to enable/disable the cutting

<img width="148" alt="cut" src="https://github.com/user-attachments/assets/0a9bf571-71b6-4c99-9954-63b896b3f769">

Because the Toolbar gets crowded, I removed the non-functioning button for `HideDuplicatesAction`
