[15_0_X] Reduce minYsizeB1 and minYsizeB2 CA cuts for Phase1

[bdanzi]

PR description:

This PR is a backport of #47271.

The PR aims to minimize the Cluster Size Cuts for the Phase 1 geometry on the B1 and B2 layers, specifically when considering B1-FPIX and B2-FPIX doublets. These doublets serve as the initial inputs for the CA. The changes have been tested on top of the Phase 1 CA-tuned parameters.

This adjustment results in about 5% relative efficiency gain in hltIter0PFlowTrackSelectionHighPurity and a 3% gain in hltMerged. Additionally, it reduces the reliance on the Doublet Recovery iteration, leading to a corresponding decrease in efficiency for hltDoubletRecoveryPFlowTrackSelectionHighPurity. Track resolution shows a small improvement as a function of pT.

Instructions on how to run

Tested in CMSSW_15_0_0_pre2 at HLT step.

Generate the .cff file on lxplus and place it inside HLTrigger/Configuration/python by running:

hltGetConfiguration /dev/CMSSW_14_2_0/GRun/V10 --globaltag 140X_mcRun3_2024_realistic_EOR3_TkDPGv7 --mc --unprescale --output minimal --max-events 500 --input file:input_file.root --cff --eras Run3_2024 --l1-emulator uGT --l1 L1Menu_Collisions2024_v1_3_0_xml --paths MC_ReducedIterativeTracking_v22 > hltMC_default_onlyTracking.py

The .cff should be loaded to run the following script:

This pull request is fully signed and it will be integrated in one of the next CMSSW_15_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_15_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @mandrenguyen, @sextonkennedy, @antoniovilela, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
