HepMcParticleLink fixes for 21.9
Expand HepMcParticleLink unit testing to match master.
Update the HepMcParticleLink
class and the HepMcParticleLinkCnv_p1
,
HepMcParticleLinkCnv_p2
, SiHitCollectionCnv_p3
and TRT_HitCollectionCnv_p4
classes
so that the expanded HepMcParticleLink
unit tests pass.
Should help fix ATLASSIM-4712.
