wayland-egl-tizen: Added new API to get presentation sync fd.

/**
 * Create a sync fence fd that can tell presentation done.
 *
 * It returns fd which tells when the presentation is finished.
 * This fd can wait asynchronously via poll or select.
 *
 * Important *
 * This fence lets caller knows when wl_surface received PRESENT or DISCARD
 *  events from the server.
 * In case of receiving DISCARD, it is not actually displayed on the display,
 *  but it releases the fence like PRESENT.
 * In most cases that are not complicated, attached buffer will not be discarded.
 *
 * @param egl_window handle to wl_egl_window.
 * @return sync fd on success, -1 on failure.
