Using SVG animate element instead of the animationFrame

[marrouchi]

I'm thinking about using the animate tag in svg instead of using the animation class in ez-core.
Docs : https://developer.mozilla.org/en-US/docs/Web/SVG/Element/animate
Examples : https://css-tricks.com/guide-svg-animations-smil/

The animation class will still be needed to animate other things like Tooltip (for the moment).

I would recommend for this change to happen gradually, meaning shape by shape to avoid possible conflicts in PRs

I've added a Proof of Concept (PoC) PR here : #87

The end result looks promising :
