ScrollView layout cycle crash

### Describe the bug

I'm getting a layout cycle error with the ScrollView control. I haven't yet been able to produce a minimal example, but it has the following characteristics.

- The ScrollViewer control was fine (just changing ScrollViewer to ScrollView with no other changes caused the crash).
- VerticalScrollBarVisibility is auto, HorizontalScrollMode is disabled.
- If I set UseLayoutRounding to false on the VerticalPanningRoot of the ScrollBar template, the crash still occurs
- If I set UseLayoutRounding to false on the ScrollView itself, the crash does not occur, however the ScrollView incorrectly shows a scroll bar when there should be none.
- If I change the vertical alignment of the content of the ScrollView to Stretch instead of Top, the crash does not occur, however the ScrollView incorrectly shows a scroll bar when there should be none.
- Issue did not occur at 100% or 150% display scaling, only 125%.

In the 'steps to reproduce' I have reproduced as much of the XAML that I can. I have also attached the layout cycle tracing below.

My feeling is that it is cycling between displaying and not displaying the scroll bar. Given that horizontal scrolling is disabled, I would expect that whether or not the vertical scrollbar is showing should have no effect on the desired height of the ScrollView. That ought to be enforced to prevent a cycle. Also, other defensive measures ought to be introduced to prevent a cycle of whether or not to show the scroll bar.

### Why is this important?

It makes the ScrollView control unusable. (Although due to the slow scrolling speed issue - https://github.com/microsoft/microsoft-ui-xaml/issues/10404 - it is already unusable).

### Steps to reproduce the bug

Cannot get minimal repro yet.

Start by reproducing the issue with the partial XAML, especially the ScrollView settings, vertical alignment, display scaling, and layout-cycle trace. Done means the layout cycle no longer crashes and the ScrollView does not show a scrollbar when no scrolling is needed; the issue does not name source files or tests to inspect.

Written by the indexing model from the issue text.
