Delegate GUI scaling work to Qt

Browse source 
Set Qt::AA_EnableHighDpiScaling application attribute when Qt 5.14.x or
newer is used. This fixes a lot of scaling issues on HiDPI displays.

Unfortunately, this flag must be set only before QApllication object
creation, so the only one place where it can be done is main().
