Liam Hupfer aa34b91856 gtk: Always read gtk-xft-dpi for font scaling
Commit ad503b8c4fa7 ("linux: consider Xft.dpi to scale the content")
introduced reading gtk-xft-dpi when the X11 build option is enabled.

While the name suggests it is X11-specific (perhaps it was at one
point), gtk-xft-dpi is a GTK setting that can be modified regardless of
GDK backend. GNOME’s Large Text accessibility setting ultimately
modifies it. Outside of desktop environments, it can be set via GTK
configuration files.

Remove the conditional gating the code on X11, since none of the code is
actually X11-specific. While we’re here, document scaling behaviors
under Config.font-size.
