Don't think exceptions in carousel panel.

`VirtualizingCarouselPanel` can't bring items into view (it can't scroll) or get a control in a direction (it only hosts one control) but we shouldn't throw `NotImplementedException` as these methods can still be called. Just make them a no-op.

Fixes #10374
