evas vector: support lottie animation as using json loader.

Summary:
This patch extends efl_canvas_vg_object class to implement efl_gfx_frame_controller
to suppor any playable animation on it.

Plus, vector object takes care of lottie animation by using json loader.
it's caching mechanism is changed to cache only static frame, not all frames.

vg_cache supports json loader and make it animation request properly.

This feature has been stabilized enough, it's using in Samsung Galaxy Watch active product,
proved its stability enough.

Depends on {D8940}
