Acts Track container reading helper algorithm

Purpose of this algorithm is to load Track Container backends and construct ActsTrk and Acts classes used by ACTS algorithmic code.

Followups:

• check surfaces
• cleanup (I consider renaming helper classes)
• symmetrise use of Aux versus interface containers

@wolter - FYI it seems the surfaces conversion is happy with just Acts::GeometryContext - I have simplified the code for it.
