Remove unused public properties

[feyst]

We already have the RemoveUnusedPrivatePropertyRector option. Would it be possible to do something similar for public properties?
If they are not used anywhere in the project then remove them?

This would require a bit different analysis than Rector can handle.

Good news§ Here is PHPStan extension that handles it
