Particle property ranges, remove ParticleRanges from P3M

[jhossbach]

Partial fix for #4721, closes #4696

Description of changes:

• Implements the ParticlePropertyRange struct containing static methods to transform a ParticleRange to a boost::iterator_range of properties of the particles, such as ForceRange or ParticleRange, which can then be used in range-based for-loops.

The refactoring of the P3M part is not finished yet, but I think this PR could also be extended to remove the ParticleRanges from the remaining Coulomb interactions.

I have successfully changed all ParticleRange signatures of methods inside the long_range_kernel method. In order to make the whole p3m.cpp free of ParticleRanges one would need to remove both the signature of long_range_kernel itself and the AssignCharge struct. The latter would require touching some other files, e.g. elc.cpp. Is this still a part of this PR or should this be moved to a larger refactoring @RudolfWeeber ?

Looks good, pending suggested changes.
