ISF_FastCaloSimParametrization: Fix ODR violation in debug build.

ISF_FastCaloSimParametrization: Fix ODR violation in debug build.

When we force code to be compiled with optimization in the debug build,
we also need to make sure that NDEBUG remains undefined.
Otherwise, we can be generating inconsistent code for Trk::ObjectCounter.
This was causing a warning when linking AtlasGeant4 in the debug build.
