[ScrollAnimation] Refactor exported components

[titouanmathis]

The ScrollAnimation family of components is large and can be confusing between the ScrollAnimation, ScrollAnimationParent, ScrollAnimationChild, ScrollAnimationWithEase, etc.

Suggestions

• Remove animationScrollWithEase, ScrollAnimation, ScrollAnimationWithEase and ScrollAnimationChildWithEase
• Rename ScrollAnimationParent to ScrollAnimationTimeline
• Rename ScrollAnimationChild to ScrollAnimationTarget

This can be done in v1.x without breaking change by deprecating the components to remove and create aliases for the new names.

Pros

• 2 components instead of 6
• a single way of using these 2 components instead of switching from ScrollAnimationChild to using data-ref="target" as target of the animation

Cons

• removing the components will be a breaking change
