Subject: [PATCH] Scale top-left coordinates in display-monitor-attributes-list

When using multiple monitors, and HiDPI, the top-left coordinates of
the monitors need to be adjusted, not just the width and height
(Bug#31223).

* xfns.c (Fx_display_monitor_attributes_list): Scale top-left
coordinates.
