xwayland/surface: Connect "highest-scale-monitor-changed" signal

Browse Source 
Similar to what MetaWaylandShellSurface does, connect the signal
"highest-scale-monitor-changed" to the handler
meta_wayland_surface_notify_highest_scale_monitor() so that
Xwaylandsurface can be notified of the fractional scale changes.
