[15_0_X] Remove EGM Scale and Smearing for Run2 reprocessing

[see-saw28]

PR description:

• Remove EGM Scale and Smearing for Run2 reprocessing. The Scale and Smearing will be apply offline on the Ecal-Tracker combined energy (instead of the Ecal energy and redo the combination for electrons) as it is done in Run3.
• Update EPcombination parameters used for combination when applying S&S on the Ecal energy. Not used anymore (see first bullet) but the wrong set of parameters was used.

PR validation:

Tested using #48176 (comment)

Hi @hqucms @ftorrresd I guess we can also merge the backport. Thanks!

As discussed in #48539 (comment), the diffs observed in the Run3 2024 reMINI workflows 2500.2601,2500.2701 are due to the misuse of the procModifier run2_miniAOD_UL_preSummer20 in these relval wfs (which will be fixed by #48686 and backported to 15_0_X too). The procModifier is not used in any Run3 production workflows, therefore no changes are expected for the ongoing production.

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, @antoniovilela, @rappoccio, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
