`SetCurrentValue`'s value was being discarded if a style with more than one setter was was re-evaluated as `ValueStore.ReevaluationEffectiveValues` removed the effective value.

`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.

Post collection changes to UI thread with higher priority than `Layout` so that all collection changes are processed before the next layout pass.
`VirtualizingStackPanel` maintains its own mapping of Items -> Containers, and updates that mapping when a `CollectionChanged` event is received, but it also expects that mapping to be up-to-date when a layout is performed.
Fixes#10399
The `PointerEnteredItem` and `PointerExitedItem` were using an obsolete API to create the event args. We don't need a `PointerEventArgs` anyway, just use `RoutedEventArgs`.
Visual tree does not work when using overlay popups because the popups are displayed as visual children of the overlay layer. This is not a problem for native popups as each popup has its own `AccessKeyHandler`.
