Move QT_FONT_DPI to cross-platform code
This makes it possible to test the effects of setting
Qt::AA_HighDpiScaling/QT_AUTO_SCREEN_SCALE_FACTOR, with different DPI
values on all platforms.
This also makes it possible to access the actual DPI values reported
by the OS/WS via the QPlatformScreen API.
A drawback is that there is no single place to check the environment
variable; currently done in three places. This may be
further simplified later on.
