layout: Add a hit test item that covers all scroll frame contents (#34347)

Browse source 
When building scroll frames, add a special
`StackingContextContent::Fragment` type for a hit test that covers all
scroll frame contents. This makes it so that you don't have to be
hovering over actual content to scroll the scroll frame.
