[desktop] Add basic carousel view (#4112)

Adds a basic carousel view, or essentially a horizontal list a la Android/Qt Quick.

Lacks a lot of niceties like autoscroll, smooth shifts, etc. Will work on those later

Also fixed a bug introduced recently that capped game icon size to 8 at the low end, breaking the None option
