Fix text scaling issues in settings UI (microsoft#17910)

## Summary of the Pull Request
Fixes some issues with truncated text in the settings UI when 200% text
scaling is applied.

For microsoft#17897, a minimum height was applied instead of a plain "height".
This ensures that the desired height is applied in general, but under
200% text scaling, we are allowed to grow past that, thus preventing the
truncation of the text.

For microsoft#17898, flyouts have a scroll viewer inside them by default. We
actually don't want the scroll viewer because that means the text will
appear "truncated" when in reality, the user is expected to notice the
small scrollbar and scroll horizontally (why that's the default, I will
never know). This PR introduces a new style that can be applied to these
flyouts to cause text wrapping instead of horizontal scrolling. Looked
through the app for any instances where this happens.

For microsoft#12006, simply changing the column width from a static value to
"auto" fixes the issue. Frankly, we care more about the text appearing
as a whole (and as whole words). The name of the actions wrap properly
anyways.
