ivi-shell: support surface screen shot of ivi_layout by using weston_surface_copy_content

Browse Source 
The reason why the result is not output in the method is that it avoids
to have dependency on CAIRO. If user want to output it to file, user
shall link CAIRO on its controller.

ivi_layout_surface_get_size is also supported here because user needs
stride to call ivi_layout_surafce_dump.
