wayland/xdg-shell: Scale positioner coordinates

Browse Source 
When the monitor is scaled (i.e. HiDPI scaling) the placement coordinates
ere still in unscaled xdg_surface window geometry coordinate space when
used to place the window. Fix this by scaling the coordinates by the
monitor scale of the parent toplevel window before using them.
