ComboBox: fix popup palette inheritance

54a2a35f17d5e5d1793af63b76993a583e10ab41 fixed the theme/accent/primary
inheritance of the Material and Universal style's ComboBox popups. This
patch makes an equivalent fix for styles that use palettes. Now the
Basic and Fusion ComboBox popups will have the correct colors in both
light and dark modes.

Fixes: QTBUG-124474
Pick-to: 6.5 6.7
