BuildEventWithConfiguration: represent configurations as BuildEvent

From a BEP point of view, the only interface of a configuration we care
about is its BuildEvent structure. Represent it as such, so that we
can move this class to the rest of the buildeventstream module. This
is a prerequisite for ActionOwners refering to configurations in the
BEP.
