Stochastics implementation header boost cleanups
There are some unguarded macro definitions (potential for redefinition) and unused boost headers (`lognormal.hpp`) in the [stochastics implementation header](https://gitlab.eclipse.org/eclipse/openpass/opSimulation/-/blob/1daaedfdee9f48d04d52113d65a39d7adec10919/sim/src/core/opSimulation/modules/Stochastics/stochastics_implementation.h#L40).
This should be cleaned up.
