[16.0.X] add reconstructable sim vertices validation for HLT full vertices

[mmusich]

backport of #49900

PR description:

Title say it all, this is a follow-up to #49609.
In that PR we introduced the concept of "reconstructable" sim-vertex, allowing the validation module to optionally focus only on sim vertices that meet reconstruction criteria (≥3 associated tracks).
We extend that validation flavor also to the "full" (offline-like, i.e. DA-driven) vertices.

PR validation:

Run the following script:

#!/bin/bash -ex

cmsDriver.py step2 --step L1P2GT,HLT:NGTScouting,VALIDATION:@hltValidation \
 --procModifier phase2LegacyPixelTracks \
 --conditions auto:phase2_realistic_T33 --processName HLTX \
 --datatier DQMIO --eventcontent DQMIO \
 --geometry ExtendedRun4D110 --customise SLHCUpgradeSimulations/Configuration/aging.customise_aging_1000 --era Phase2C17I13M9 \
 --inputCommands='keep *, drop *_hlt*_*_HLT, drop triggerTriggerFilterObjectWithRefs_l1t*_*_HLT' \
 --filein file:/eos/cms/store/relval/CMSSW_16_0_0_pre4/RelValTTbar_14TeV/GEN-SIM-DIGI-RAW/PU_150X_mcRun4_realistic_v1_STD_Run4D110_PU-v2/2580000/037118f1-472e-4647-88fc-b0211e52df6f.root \
 --fileout file:step2.root -n -1 --nThreads 0

cmsDriver.py step3 -s HARVESTING:@hltValidation --filetype DQM \
 --conditions auto:phase2_realistic_T33 --geometry ExtendedRun4D110 \
 --scenario pp --mc --era Phase2C17I13M9 \
 -n -1 --filein file:step2.root

and checked that the output DQM file is sensible.

This pull request is fully signed and it will be integrated in one of the next CMSSW_16_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_16_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @ftenchini, @sextonkennedy, @mandrenguyen (and backports should be raised in the release meeting by the corresponding L2)
