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 :

```

#include <stdio.h>

#include <Eina.h>
#include <Ecore.h>
#include <Evas.h>

    }

      printf("duration    : %f\n", evas_object_image_animated_frame_duration_get(o,1,0));
      printf("loop count  : %d\n", evas_object_image_animated_loop_count_get(o));
      fflush(stdout);

    }
