Wayland drag-n-drop: handle subwindows as other platforms do (#516)
The d-n-d target window is now always the top-level window even if the
mouse is over a subwindow. That's what all other platforms do.
Global var fl_dnd_target_surface memorise what's the current d-n-d target
surface and follows changes from top-window to subwindows.
