Updates to new HLT2 trigger line for dark photon search

This is a new merge request on top of !2207 (merged).

The new changes are:

• A new way to save the persistable selection from the WeightedRelTableAlg where its implementation is done by extending the already existing make_photons_to_preserve function.
• Add the []cc missing in the DecayDescriptor of 2 two trigger lines.

This merge request depends on the new function SelectionFromWeightedRelationTable implemented on Rec!3434 (merged), working on local stack.

Now the warming messages are gone:

# WARNING: Unsupported type <class 'RelatedInfoTools.RelatedInfoToolsConf.WeightedRelTableAlg'> for line output WeightedRelTableAlg/WeightedRelTableAlg_f0b45839 (for location ('Hlt2Charm_Dst0ToD0EmEp_D0ToKmPip',)); this will not be persisted
