[beats/management] Move breadcrumbs to chrome

[spalger]

See the #25884 for more general information.

It appears that BCM uses its own breadcrumbs component rather than integrating with the breadcrumbs handled by management. Before the k7 design this was a little unexpected, but less problematic. Now that breadcrumbs are a much more core navigational concept we need to align BCM with the rest of the management sections and move breadcrumbs to use chrome.breadcrumbs.set() instead.
