[Breadcrumbs]: allow React component to accept additional attributes

[jendowns]

Summary

Currently the Breadcrumbs React component does not have a spread attribute, so a user cannot pass in anything outside of the defined props to be rendered, like an id.

Justification

I think it is reasonable to expect an end user to want to pass in an id attribute, for example, to a component and have that be rendered in the DOM. There are also data attributes that different application may need to pass in.

By adding a spread attribute to the component, Breadcrumbs would be able to accept these additional attributes.
