wayland: remove manual CSD geometry offset from scene positioning 

wlr_scene_xdg_surface_create handles geometry offset internally.
Our manual subtraction of geometry.x/y in handle_toplevel_commit,
handle_toplevel_map, and wl_window_move was double-subtracting,
causing client surfaces to render behind their frames.

Remove all manual geometry offset from scene node positioning.
