Allow more succinct invocations with passthru args.

If passthru args "belong" to a goal scope then all tasks in that goal get them.
E.g., you can do:
pants goal run <python-target> -- passthru args
and the run.py task will get the passthru args. So will run.jvm, but that's OK
because it's a no-op for <python-target>.
This obviously is only good when in practice only one passthru-arg-supporting
task in that goal is not a no-op. However that is the common case.
