Introduce separate title and subtitle styles for list item

### Your use case

Currently many list items use `Widget.Vector.TextView.Subtitle` as a style for `title` with overridden colour. This style doesn't refer to list item so it could happen that changing that style will lead to unexpected changes in appearance.

To mitigate this problem separate set of styles should be created for list items and applied to them across the app
