Add support for drawing a hyperlink in QPdfEngine
Adds the drawHyperlink method so that clients can draw a hyperlink
pointing to the specified URL at the specified rectangle. That new
method is to be used by GraphicContext::setURLForRect implementations
that want to render anchors as clickable links in PDF documents.
Task-number: QTBUG-44563
