Test algorithm with internal multithreading

Since this is a design goal of GaudiHive/AthenaMT, adding a test to ensure that algorithms can actually use internal multithreading via TBB.

At the moment just uses TBB parallel_for. Could add a more comprehensive test with task_group if that would be valuable?

While it was indeed one of the design goals, I advise not to promote this possibility to Athena users at this point. There are nuances. In the current Athena configuration, the intra-algorithm parallelism will most likely lead to lower throughput.
