wayland/surface: Add API to cache frame callbacks
Sometimes it may be useful for roles to put callbacks in the generic
surface frame callback queue. The surface frame callback queue will
either eventually be processed on the next surface role assignment that
places the frame callbacks in a role specific queue, processed at some
other point in time by a role, or cleaned up on surface destruction.
