support X11::GlobalScaling properly

--as it appears many users are using Plasma GlobalScaling
in conjuction with PLASMA_USE_QT_SCALING. This commit
provides plenty of fixes for that scenario in order to
make things workable.
--adjust X11::InputMask based on devicePixelRatio()
--adjust X11::GtkFrameExtents based on devicePixelRatio()
--adjust View::absoluteGeometry() based on devicePixelRatio()
--adjust WM::Tracker based on devicePixelRatio()
--adjust WM::AbstractInterface based on devicePixelRatio()
