QIconLoaderEngine: use scaledPixmap() to properly pass dpr

Browse Source 
QIconLoaderEngine::paint() was still using QIconLoader::pixmap() to
retrieve the pixmap for painting instead QIconLoader::scaledPixmap()
which takes the devicePixelRatio as additional parameter. In the case
of icon themes this could pick up the wrong pixmap (from the wrong
folder).

Pick-to: 6.8
Fixes: QTBUG-135159
