vg_common_json: Override value_provider list

Summary:
If value_provider is applied to Efl.Ui.Animation_View, it is passed as vector object.
The passed value_provider list passes to Vg_File_Data.
If there is a value_Provider list in Vg_File_Data,
it apply the property to Lottie_Animation using lottie_animation_property_override api.

Depends on D9874

Test Plan:
...

Eo *vp = efl_add(EFL_GFX_VG_VALUE_PROVIDER_CLASS, p);
efl_gfx_vg_value_provider_keypath_set(vp, "**");
efl_gfx_vg_value_provider_fill_color_set(vp, 100, 0 ,0 ,255);
efl_ui_animation_view_value_provider_override(anim_view, vp);

vp = efl_add(EFL_GFX_VG_VALUE_PROVIDER_CLASS, p);
efl_gfx_vg_value_provider_keypath_set(vp, "**");
efl_gfx_vg_value_provider_stroke_width_set(vp, 50.0);
efl_gfx_vg_value_provider_stroke_color_set(vp, 0, 255, 0, 100);
efl_ui_animation_view_value_provider_override(anim_view, vp);
