QStyleSheetStyle: ItemViews: Fixes drawing of items and branches.

I am not sure why the code was there, but after some testing, it is better
to remove it:

 - While painting the branch, we should not look at the ::item pseudo class
   at all.
 - Items specific stuff is drawn in PE_PanelItemViewItem, not PE_PanelItemViewRow
 - Selection is handled his way by the native style. background-color is not for
   selection and should not depends on SH_ItemView_ShowDecorationSelected
