- Inherit CarouselPanel from VirtualizingPanel, use ItemsStackPanelLayout
 - amend ComboBox style to support virtualization

Make the case more robust where the list initially measures with a smaller desired size than what is available, ie the items don't fill all available space.

This fixes a bug with the former logic where, after returning a smaller desired size than what was available, the list would be remeasured with that returned size, and then 'forget' that more space had been available.

Fix layout attributes not updating with dynamic sizes correctly, it seems that in some cases PreferredLayoutAttributesFittingAttributes() may be called out of order.

This can occur when Measure() is called outside of the usual loop, followed by ScrollIntoView().

If SelectedItem is a view, ensure it's correctly placed in either the ContentPresenter or the dropdown list according to whether the dropdown is open.

This fixes bug where the item would disappear from the ContentPresenter if the dropdown were light-dismissed without changing the selection, and makes the logic more robust in the case of a virtualized list.

Certain Styles application sequences can lead to the same ItemsPanelTemplate (but not reference-equal) being applied multiple times.

As a perf improvement, don't reapply the panel. This also works around the issue on Android that changing the ItemsPanel of a ListView after it's already been materialized isn't properly supported and causes errors.

This is a significant perf optimization since UpdateLayout() is called very frequently while scrolling.

When ListView has non-Stretched breadth, item elements must be arranged with the list's breadth rather than their desired size. (Otherwise, eg, selected state highlight doesn't stretch to full width.)

Revert virtualization on these platforms because it breaks layouting (ComboBox dropdown stretches to full width of window). It can be reenabled when #1133 is fixed.
