eglfs: Enable use of Qt::AA_EnableHighDpiScaling
Support use of Qt::AA_EnableHighDpiScaling and
QT_AUTO_SCREEN_SCALE_FACTOR.
This makes the high-dpi scaling system use the screen
configuration set with QT_QPA_EGLFS_PHYSICAL_WIDTH and
QT_QPA_EGLFS_PHYSICAL_HEIGHT.
Implement QEglFSScreen::pixelDensity() and make it return
the scale factor for the display. The scale factor is computed
as the ratio of the logical DPI to the base DPI.
