A number of constexpr particle constants to avoid hardcoding them directly in various places.
This is not meant ot be a complete list of everything that could be needed, please look that up from the PDG database, this is just for numbers that would otherwise have to be hard-coded because it can't (practically) do that lookup.
Please note that while you should feel free to add new constants here, you need to also add them to the testParticleConstants.cxx test, so that we can ensure that the values here match the values in the ParticleDataTable.
