backporting gen filter to CMSSW_10_6_X

[danielwinterbottom]

PR description:

Backport of #27791 modifying EmbeddingHepMCFilter:

• Setting the boson PDGID under option so that the filter can be used for Higgs events
• Adding booleans to make sure the correct tau decay types are identified in cases where there are additional FSR photons
  These modifications are needed so that we can use this filter for a UL MC request.
  This filter was already backported and used successfully for pre-UL MC campaigns, but it is needed now for UL MC requests requiring a backport to CMSSW_10_6_X as well.
  The filter reduces the required statistics for our samples by a factor of 4 - without this filter the size of the sample required would be unfeasible to produce.

PR validation:

• Checked that the modifications compile in CMSSW_10_6_29_patch1
• These modifications were already tested and used successfully used for several MC productions for pre-UL samples

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

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_12_3_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)
