Carbon React TooltipIcon component should accept a renderIcon prop

[John30013]

Summary

The current TooltipIcon implementation requires including the icon as a child element. Most other Carbon React components that include an icon do so via the renderIcon prop. I'm requesting that you update TooltipIcon to follow this pattern, and allow specifying the icon via a renderIcon prop.

Justification

This change would provide a programming interface that is consistent with other Carbon React components that display an icon (Button, Link, OverflowMenu, and Tag).

Desired UX and success metrics

Developers would be able to use a consistent programming interface to specify the icon to be rendered by any Carbon React component that can render an icon.

I'm sure I could implement this myself, but it would take some time as I would need to study other Carbon React components that implement the renderIcon prop to see how it's done. It would probably be faster for someone on the Carbon React development team to do this. But I'll be glad to give it a shot.

Carbon is a collaborative system. We encourage teams to build components and
submit them for integration as either add-ons or core components.
