[backport] Change at CaloLayer1 DQM the filling threshold for ECAL 5BX plots

[hftsoi]

PR description:

This PR is to modify the CaloLayer1 DQM, raising the TP energy threshold for filling the FAT event histograms for ECAL's pre-firing studies. The old threshold has been at 1 GeV, which is too low and the plots are dominated by detector noise seen in previous cosmic runs. The new threshold is set at 4 GeV, which should be well above the average noise levels reported by ECAL. Filling conditions are also added to be consistent with normal events filling, i.e. do not fill if there is problematic tower masked etc.

PR validation:

The codes are tested by running offline DQM on recent runs with unstable beams collisions, which has more high energy TPs to see the real effects. The DQM plots are properly filled and the ECAL experts are satisfied with this modification.

if this PR is a backport please specify the original PR and why you need to backport that PR:

PR to master: #38361
This backport is for integrating into online DQM production, currently based on CMSSW_12_3_5_patch1.

This pull request is fully signed and it will be integrated in one of the next CMSSW_12_3_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_5_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
