Standardize the className, style and children props.

[alexasselin008]

All RAC components allows className, style and children to be function, where the parameters are the component's state, and the return value the className to append.

<Checkbox className={({isDisabled}) => isDisabled ? "disabled" : "enabled" />

However, some of our component that are not based on react aria do not allow such function, such as the Chip component.
We should make sure that all component with a state (not the stylistic stuff like variant/fluid/size) should allow those functions

For instance, the Avatar, or basically any component extending BaseComponent, aka not RAC component, do not have render props for classname, style and children

There was 2 PRs for this:

• Fix bad usage of useRenderProps #423
• [DS-283] Standardizing className, style and children Props for BaseComponentProps #424

Not sure if I missed any, so I didn't close it.
