Allow attributes on breadcrumb items

[nikolab-pn]

Describe the feature request
It is possible to add html attributes tags to breadcrumb elements

Describe the use case
Having application that supports english and german UI and user defined content it can happen that part of breadcrumbs is in different language. In this case it is recommented to use lang="" on such elements. It is not possible to do this with current implementation of breadcrumbs.

HI @nikolab-pn can you maybe provide more information about this. Because this seems to be something that can be set in run time from the Ui-library or even js code. Can you maybe elaborate on the concrete issue this would solve and how it would exactly be used .
