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.

Dear experts, I would be most happy about comments on where things are placed. I.e. packages/alg names etc. As you see I have used liberty to decide, but I am sure better choices can be made.

changed the description

I looked the code over and found no problems with it, but due to the extensive changes, I'm giving this over to L2 for a more competent opinion.

Cheers, Yuriy (L1)

removed review-pending-level-1 label

Just a few minor points to consider but overall it looks good.

Best, Thomas - L2
