    gdk/wayland/surface: Expose gdk_wayland_surface_get_wl_egl_window()
    
    Some GTK based applications such as Qemu UI create and manage
    EGLSurfaces associated with the relevant GdkSurfaces. In order to create
    an EGLSurface, there needs to be a way to pass the native window
    object to eglCreateWindowSurface(). While running in an X environment,
    the native window object can be obtained by calling
    gdk_x11_surface_get_xid(). Likewise, the native window object can be
    obtained by calling gdk_wayland_surface_get_wl_egl_window() while
    running in a Wayland environment. Therefore, this API needs to be
    exposed to apps.
