Adding HepMC3 products to EDMProduct

[SiewYan]

PR description:

This PR trying to address the EDM addition in #37187 , using advises from twiki [*]. The HepMC3 package adapted new strategy to manipulate event records of High Energy Physics Monte Carlo Event Generators (MCEGs) [**], notably:

1. Particles and vertices are stored separately in an ordered graph structure; all custom iterators were removed.
2. Extension on the I/O functionality of the library.

The HepMC3 new data format poses challenges on defining the corresponding EDMProduct definition.

This PR depicts partial implementation, due to some technical error:

Error: Class shared_ptr<HepMC3::GenParticle> has been selected but currently the support for its I/O is not yet available. Note that shared_ptr<HepMC3::GenParticle>, even if not selected, will be available for interpreted code.
Error: Class shared_ptr<HepMC3::GenVertex> has been selected but currently the support for its I/O is not yet available. Note that shared_ptr<HepMC3::GenVertex>, even if not selected, will be available for interpreted code.

I am looking for advice(s) on how to solve the error. @smuzaffar, @mkirsano

Note: class version will be done accordingly after a successful compilation with the amended version classes_def.xml.
