New E/g HLT Pixel Matching : 91X (really for 91X this time)

[Sam-Harper]

This is the 91X flavour of #18541 which ended up going for 92X.

This PR is unfortunately necessary to be able to run the E/gamma HLT efficiently with the phaseI pixels and as such needs to be 91X.

This pull request is fully signed and it will be integrated in one of the next CMSSW_9_1_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_9_2_X is complete. This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @smuzaffar
