ensure HLTProcess adds all (End)Paths to the schedule [12.2.X]

[missirol]

backport of #36422

PR description:

This PR updates HLTProcess (which controls the output of hltGetConfiguration), ensuring that (End)Paths appended by HLTProcess are added to the schedule.

For example, if one currently specifies --output minimal, the corresponding output .root file is not produced.

The issue was spotted by @silviodonato.

PR validation:

Manual tests, e.g.

for ec in minimal full all none ; do
  hltGetConfiguration /dev/CMSSW_12_2_0/GRun --globaltag auto:run3_hlt --data \
    --customise HLTrigger/Configuration/customizeHLTforCMSSW.customiseFor2018Input \
    --input /store/data/Run2018D/EphemeralHLTPhysics7/RAW/v1/000/323/790/00000/B543D251-40F1-CB46-A6A1-046CF3D78D6D.root \
    --era Run2_2018 --output ${ec} --max-events 10 > hlt_${ec}.py
  cmsRun hlt_${ec}.py &> hlt_${ec}.log
  ls -ltra .
done
unset ec
