[15.1.X] add support for multiple input FEDs in HLTL1NumberFilter

[mmusich]

backport of #48957

PR description:

From the original PR description:

Title says it all: the DAQ group is preparing the global system for running with the secondary TCDS system, where FED 1050 would be present as TCDS FED instead of 1024, see more details at CMSHLT-3643.
Considering HLT, they went through the modules consuming FED 1024 and they found that the module HLTL1NumberFilter does not support multiple FED input values, thus it can work with both FED IDs in global HLT.
The goal of this PR is to support multiple TCDS FEDs in input.

PR validation:

TSG integration tests: addOnTests.py works.

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:

Verbatim backport of #48957 to the 2025 PbPb data-taking release, for online tests.

This pull request is fully signed and it will be integrated in one of the next CMSSW_15_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_16_0_X is complete. This pull request will now be reviewed by the release team before it's merged. @mandrenguyen, @ftenchini, @sextonkennedy (and backports should be raised in the release meeting by the corresponding L2)
