Evas: add avif evas loader and saver
...
Summary:
Add AV1 image file loader and saver to Evas
The loader can be tested with this code :
```

{

i++;
return ECORE_CALLBACK_RENEW;
}
return ECORE_CALLBACK_DONE;
}

{

return 1;
}
evas_object_image_size_get(o, &w, &h);
evas_object_image_fill_set(o, 0, 0, w, h);
evas_object_move(o, 0, 0);
evas_object_resize(o, w, h);
evas_object_show(o);

}

ecore_evas_shutdown();

}
