xprofile: Run dpi script on startup

Ensures configuration of various graphical services is set correctly on
startup, either before they start, or just after, restarting them
accordingly. This should scale i3, picom, gtk and friends for a seamless
experience.

Use xresources as a source of truth for this information.
