Improve debug operator for QGraphicsItem/QGraphicsObject.

Browse Source 
Introduce QDebugStateSaver, use new formatting helpers and
output parent, flags and z only when necessary. Output the
widget contained in QGraphicsProxyWidget.

For example,

QGraphicsProxyWidget (this = 0x1877550 , parent = 0x0 , pos = QPointF(870,491) , z = 1e+30 , flags =  ( ItemIsFocusable | ItemUsesExtendedStyleOpton | ItemSendsGeometryChanges | ItemIsPanel ) )

becomes:

QGraphicsProxyWidget(0x1877550, widget=ItemDialog(0x1e29dc0), pos=870,491, z=1e+30, flags=(ItemIsFocusable|ItemUsesExtendedStyleOption|ItemSendsGeometryChanges|ItemIsPanel))
