QGraphicsWidget: overload two margins-setters with actual QMarginsF overloads

Replace manual memory management with unique_ptr and manual
re-implementations of QMarginsF with The Real Thing™.

The only noticeable difference should be that the checks for 0 now use
qFuzzyCompare() (by way of QMarginsF::isNull() and its operator==).

[ChangeLog][QtWidgets][QGraphicsWidget] Added QMarginsF overloads of
setContentsMargins() and setWindowFrameMargins().
