qt_paint_device_metric() for fetching metrics

Custom window surfaces, graphics systems, and Qt/Embedded screen
drivers often need to access QPaintDevice::metric(), but it is
protected.  Hence the growing number of friends in QWidget and
QImage.  The qt_paint_device_metric() function provides a more
future-proof approach that doesn't require lots of friends.
