wayland-egl: Added new API to set window serial.

 - New wayland-egl-tizen API :
 void
  wl_egl_window_tizen_set_window_serial(struct wl_egl_window *egl_window,
					unsigned int serial)

 - If client use this new API, increaing wl_egl_window->serial will not
  work at dequeue, and buffer's serial value will be set to the serial
  that the client passed to this API.
'- The serial value client want to set must be incremented
  whenever there is a change related to the window.
 - This API should be called before the gl first draw call to ensure
  the correct one frame in the desired serial.
