Port QtBase to the new QIcon::pixmap() API

The target devicePixelRatio can now be passed to the
pixmap() function, instead of a QWindow pointer.

This allows us to remove some usage of the QWidget pointer
in the styles, since the DPR is accessible from the passed
in painter. The QWidget pointer is still used in places where
we don't have a painter.
