xdg-shell: Move "ping" and "pong" to xdg_shell, not xdg_surface
Responsivenes is a per-client thing so we move the ping/pong functionality to xdg_shell. Having this per-window was carries over from the EWMH protocol, where the WM has no other way to do this. In wayland, the compositor can directly ping the client that owns the surface.
