Software backend: fix PaintedItem smooth xform

When a transform is applied to a QQuickPaintedItem, its 'smooth'
property should determine whether the transform is done with
antialising or not. This worked as expected with the default (rhi)
backend, but not with the software backend.

Since transforms do not cause item repaint, but are used when painting
the item's earlier painted and cached pixmap, the antialiasing is
determined not by QPainter's Antialiasing render hint, but by the
SmoothPixmapTransformation hint.

Fix by applying that hint according to the 'smooth' property value.
