Add option to disable new minimize/maximize/restore/close buttons due to bug with custom dialogs

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.71.0
• OS Version: Windows 11

Steps to Reproduce:

1. Enable custom dialogs ("window.dialogStyle": "custom")
2. Create a new file
3. Try to close it

Please try "window.experimental.windowControlsOverlay.enabled": false (requires VS Code restart)

Works, thanks! Is it expected to be like this or as a temporary setting?
