Drop call to setPlatformScreen in QHighDpiScaling::setScreenFactor

Drop call to setPlatformScreen since the only affected variables are
logicalDpi and geometry. Replace setPlatformScreen with updateLogicalDpi
which handles global scale factor changes in QScreen.

Call updateGeometriesWithSignals() to check if there are any changes
in geometry or availableGeometry, since the geometry or availableGeometry
can also change when setting a scale factor.

Move setPlatformScreen to QScreen ctor as the function is not used
elsewhere.
