wayland/xdg-shell: Scale positioner coordinates

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.

-----

Rewrote the first patch to scale the coordinates as a more sane place. Also
added a comment documenting the coordinate space of the stored placement rule
fields.
