[Breadcrumb] refactor hasOverflow to use implementation from Carbon

[tay1orjones]

What package is this for?

• React
• Angular

Summary

The Carbon team is updating the breadcrumb to have first-party support for the overflow menu. We'll need to make some changes to our hasOverflow implementation to take advantage of the feature now provided by the base component.

Note that this is only support for the overflow menu - we'll need to retain our feature of automatically adding/removing items in to and out of the overflow menu on browser resize.

Carbon PR: carbon-design-system/carbon#7085

Specific timeline issues / requests

This will probably be contained as part of an upgrade of our Carbon dependencies. Potentially v10.23.0 (#1702), but more likely v10.24.0
