Backport #18353 to 90X, plus update TP nsamples and adc2fC

[DryRun]

Backports #18353 to 9_0_2 for online DQM.

For correcting the number of samples in HF TP emulation, I merged the following:

• 8783cd3 from https://github.com/christopheralanwest/cmssw/commits/correct_hcal_presamples_90X,
• Use presamples and sample variables correctly for HF TP #18170
• HCAL DQM update for 9_0_X #17882

I also changed the adc2fC conversion to use the DB values as in normal reconstruction, rather than a hard-coded lookup table.

These additional two items will be incorporated into the next PR to 9_1_X (coordinate with the TP nsamples PRs).
