refactor: Remove redundant check in MultiWireStructureBuilder (acts-p…

…roject#2824)

I removed some lines that check the dimensions of the trapezoid bounds since it is already checked in the volume structure builder that is called in the `construct` method of the `MultiWireStructureBuilder. `
Also, it does not allow for passing six parameters and using the six-parameter constructor of the `TrapezoidVolumeBounds`
I need to get rid of this in order to be able to pass all the bound values (six values) when constructing the bounds of MDTS in athena: 

` std::unique_ptr<Acts::TrapezoidVolumeBounds> mdtBounds = std::make_unique<Acts::TrapezoidVolumeBounds>(parameters.shortHalfX, parameters.longHalfX, parameters.halfY, parameters.halfHeight);
       mlCfg.mlBounds= mdtBounds->values();
                     `
