update of L1TGlobalProducer to handle fractional prescales [12_5_X]

[missirol]

backport of #39464
backport of #39832

PR description:

This PR backports #39464 and #39832. The first one is a fix by the L1T group to correctly apply fractional prescales in L1T software (needed, for example, for the development of the HIon menu); the 2nd PR is a technical follow-up of the 1st one, adding a unit test and small technical improvements.

Because of #39832, this PR requires the backport of cms-sw/cmsdist#8140 to the 12_5_X branch of cmsdist.

On top of the backports, there is one more commit (844f35a): I had to change the input file of the unit test to use a 12_5_X file.

FYI: @elfontan @mitaylor

PR validation:

The new unit test passes in local tests.

If this PR is a backport, please specify the original PR and why you need to backport that PR. If this PR will be backported, please specify to which release cycle the backport is meant for:

#39464
#39832

Fix for offline trigger studies.

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_12_5_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_6_X is complete. This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)

[missirol]

This PR should be merged "with" (same IB), or after, cms-sw/cmsdist#8146.
