Make title of DetailedList on Windows more prominent

What is the problem or limitation you are having?

On Windows and Qt, the title of DetailedList is in the same font as the sub title.

Describe the solution you'd like

The title should be more prominent. It should be rendered using the default font face and size for the platform; the subtitle should use a font that is 20% smaller than the default font size.

Describe alternatives you've considered

Additional context

On other platforms, the title is more prominent than the sub title. This can be confirmed visually in the screenshots in the API guide. These screenshots should be updated as part of the PR addressing this issue. The "screenshots" example app can be used to generate the required screenshot images.
