High-DPI: Use correct DPI for QT_USE_PHYSICAL_DPI
Setting the QT_USE_PHYSICAL_DPI environment variable
will make Qt use physical DPI when determining the
screen scale factor, instead of logical DPI.
However, the code was using QScreen::physicalDotsPerInch(),
Whose return value is itself scaled by the device
pixel ratio. (See QTBUG-62649 for further discussion).
Use QPlatformScreen API instead and calculate the DPI
based on geometry() and physicalSize().
Pick-to: 5.15
