[iOS] CarouselView doesn't scroll to the right Position after changing the ItemSource with Loop enabled

[PureWeen]

Description

iOS version of https://github.com/dotnet/maui/issues/17283

After the Carousel ItemSource is loaded for the first time, try to reset or assign a new ItemSource and set the Position to a specific value right after that with the Loop property enabled, the Carousel won't scroll to the right item. If we disable the Loop property, the scroll works fine. I could reproduce it on Android and iOS.

Steps to Reproduce

1 - Create a new project .NET MAUI App 2 - Add a Carousel to the page with the Loop = True 3 - Load a list of 3+ items into the Carousel ItemSource 4 - Swipe it to the last position 5 - Replace the item source list or assign a new one. It could be the same list, but it needs to reset the ItemSource. 6 - Try to set the position again to the last item programmatically right after reloading the list. 7 - If you disable the loop it works.

Expected outcome: The last item should be selected Actual outcome: The first item will be selected, and the swipe feature will get lost
