Split out some inline qdebug formatting helpers to qdebug_p.h.
Extract helpers to be able to format classes without type names
and use those for formatting QEvents to reduce clutter.
For example:
QWidgetWindow/"MainWindowClassWindow" QMouseEvent(QEvent::Type(MouseMove), buttons=QFlags<Qt::MouseButtons>(LeftButton), localPos=QPointF(50,116), screenPos=QPointF(948,652))
QWidget/"qt_scrollarea_viewport" QMouseEvent(QEvent::Type(MouseMove), buttons=QFlags<Qt::MouseButtons>(LeftButton), localPos=QPointF(45,32), screenPos=QPointF(948,652))
becomes
QWidgetWindow/"MainWindowClassWindow" QMouseEvent(MouseMove, LeftButton, localPos=50,116, screenPos=948,652)
QWidget/"qt_scrollarea_viewport" QMouseEvent(MouseMove, LeftButton, localPos=45,32, screenPos=948,652)
