[12.6.X] Ensure that egamma picks up 2023 HB thresholds for 12_6_X MC production

[swagata87]

PR description:

This is to ensure that egamma reco picks up updated HB recHit thresholds for 12_6_X MC production.

A new Era called Run3_2023 is introduced: Configuration/Eras/python/Era_Run3_2023_cff.py .

At the time of opening this PR, Era_Run3_2023_cff.py and Era_Run3_cff.py are basically same, the only notable difference is that run3_egamma_2023 is included in ModifierChain of Run3_2023.

PR validation:

After doing this:
cmsDriver.py step3 -s RAW2DIGI,L1Reco,RECO,RECOSIM,PAT,NANO,VALIDATION:@standardValidation+@miniAODValidation,DQM:@standardDQM+@ExtraHLT+@miniAODDQM+@nanoAODDQM --conditions auto:phase1_2023_realistic --datatier GEN-SIM-RECO,MINIAODSIM,NANOAODSIM,DQMIO -n 10 --eventcontent RECOSIM,MINIAODSIM,NANOEDMAODSIM,DQM --geometry DB:Extended --era Run3_2023 --filein file:step2.root --fileout file:step3.root --customise RecoParticleFlow/PFClusterProducer/particleFlow_HB2023.customiseHB2023 --no_exec

obtained step3_RAW2DIGI_L1Reco_RECO_RECOSIM_PAT_NANO_VALIDATION_DQM.py.

Then, edmConfigDump step3_RAW2DIGI_L1Reco_RECO_RECOSIM_PAT_NANO_VALIDATION_DQM.py > dump_1.py;

Checked by doing grep recHitEThresholdHB dump_1.py that correct HB thresholds were picked up everywhere; i.e.
recHitEThresholdHB = cms.vdouble(0.4, 0.3, 0.3, 0.3), in dump_1.py.

Checked that step3_RAW2DIGI_L1Reco_RECO_RECOSIM_PAT_NANO_VALIDATION_DQM.py runs fine on a proper input root file.

Note that --customise RecoParticleFlow/PFClusterProducer/particleFlow_HB2023.customiseHB2023 is available
via #40689

There is no corresponding PR for master branch, as discussed with PPD. For now, this change is needed only for 12_6_X MC production. Studies based on the upcoming 12_6_X MC would tell us if these changes need to be propagated to the 2023 data-taking release (13_X) or not.

It would be clearer to define the Run3_2023 era as

• It defines a new Run3_2023 era (not used in the current production workflows) to pick up the new HB thresholds in some special test production
