window: allow for updating size from current geometry.

Add gst_vaapi_window_reconfigure() interface to force an update of
the GstVaapiWindow "soft" size, based on the current geometry of the
underlying native window.

This can be useful for instance to synchronize the window size when
the user changed it.

Thanks to Fabrice Bellet for rebasing the patch.

[changed interface to gst_vaapi_window_reconfigure()]
