Subject: [PATCH] QWidget: update the font when the screen is changed

The screen may change the dpi so the font dpi is also changed.
We must tell QWidget that the font has changed by sending the
FontChanged event to all sub widgets so they can update their
geometry.

Task-number: QTBUG-48242
Change-Id: Ibcdcc0c96429b8cd16311928298294f47a23e816
