Title: support DependentConfiguration combinations,

including e.g. formatString("%s:%d", attrWhenReady(A), aWR(b)),
with tests

and easier to set blocking details when something is blocked, and done better and in more places
(but we still don't have a nice way to show child _tasks_ when a parent is blocked on a child)

and deprecated the unnecessary (and wrong) use of ExecMgr field in BasicTask with pointer to current ExecCtx (only used for CompoundTask)
