Aleix Pol f42a3bad65 Drop libkscreen dependency
Drops the x11 fallback. We were falling back to QX11Extras that were in
fact using QScreen internally.
Also remove the QDesktopWidget fallbacks for the same reason.
Drops some API for fetching the dpi and unifies it with ::realDpi(QWidget).

Based on Sebas's patch.
Reviewed by Albert.
