Clean up RedistributeCPU (#4529)

## 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.
