Qt Designer: Add customizable property tooltips.
- Introduce tag propertytooltip to property specifications
in the ui XML snippet returned by
QDesignerCustomWidgetInterface::domXml()
- Pass the text to the property editor and set as description tooltip
on the property.
- As an added benefit, show the type in the normal tooltip.
- Demonstrate using TicTacToe example.
[ChangeLog][Qt Designer] Added customizable property tooltips.
Task-number: QTBUG-45442
