Clean up RedistributeCPU

[AlexanderSinn]

Summary

This PR simplifies RedistributeCPU to be independent of particle layout in preparation for #4404. For this, push_back is replaced by a resize with a geometric growth strategy. push_back is error-prone due to having the possibility to desynchronize the sizes of the individual component vectors if used incorrectly.
