Don't render PE_PanelItemViewRow under tree decoration if style says no

Fusion style's SH_ItemView_ShowDecorationSelected hint is hard-coded to 1,
but in QCommonStyle::drawPrimitive (which QFusionStyle inherits) it only
asked its own QFusionStyle::styleHint() before drawing the background that
happens to be under the tree row decoration (arrow thingy or +/- symbol).
And the style doing the rendering does not know about QStyleSheetStyle so
by the time we get to QCommonStyle::drawPrimitive() it's too late to check.
Therefore QTreeView needs to avoid calling it in this case.
