DualListSelector/TreeView/Form - remove opt-in animation logic

[thatblindgeye]

Describe the enhancement or change
In the next breaking change release, we need to remove the opt-in logic for animations in these components so that animations are on by default. This will include at least removing any hasAnimations prop as well as ensuring any children are rendered always (rather than only when a parent item isExpanded).

Applicable PRs:

• feat(Form): enabled opt-in animations for expandable fieldgroup #11843
• feat(DualListSelector): enabled opt-in animations #11837
• feat(TreeView): enabled opt-in animations #11842

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?
