Implement the GSF Track fBrem Variable Filling for Scouting Electrons: 14_0

[arsahasransu]

PR description:

• The fBrem variable is reconstructed at the HLT with PR43774.
• This PR enables its accessibility to the Scouting Egamma Producer and fills the electron collection appropriately.
• The default values in HLTScoutingEgammaProducer::fillDescriptions changed to reflect the values as expected in the path that uses the producer.
• Backport of PR43873 in the 14_1_X release cycle.

PR validation:

• The standards code check and formatting have been completed successfully.
• I re-ran the recommended HLT config - /dev/CMSSW_13_3_0/GRun - with the changes in this PR on the Double Electron Gun MC and checked the variable fill. Screenshot is attached below and shows that the variable is correctly filled. The config and the output can be found in CERN AFS at the path /afs/cern.ch/work/a/asahasra/public/ScoutingStudy/For2024ScoutingEGUpdate/TestSecondRoundOfCommits/CMSSW_14_0_0_pre3/src and are named as configHLT1330V22Fbrem_ScoutingPF.py and outputHLT1330V22Fbrem_ScoutingPF.root respectively.
• The relevant for the customisation for the menu is at the path /afs/cern.ch/work/a/asahasra/public/ScoutingStudy/For2024ScoutingEGUpdate/TestSecondRoundOfCommits/CMSSW_14_0_0_pre3/src/HLTrigger/Configuration/python/customizeHLTforScouting.py.

• verbatim backport of Implement the GSF Track fBrem Variable Filling for Scouting Electrons: 14_1 #43873 (the very same branch is used).

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_14_0_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_14_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @rappoccio, @sextonkennedy, @antoniovilela (and backports should be raised in the release meeting by the corresponding L2)
