Add "Script" iOS 18 ControlWidget (#2952)

## Summary
<!-- Provide a brief summary of the changes you have made and most
importantly what they aim to achieve -->
This PR also adds a dependency: `SFSafeSymbols` to safely iterate over
SFSymbols. For ControlWidget we can't use MaterialDesign icons, unless
they are converted into custom SFSymbols and embedded in the App but
this would increase a lot the App size

## Screenshots
