[EGM] Remove obsolete Phase2 configs

[swagata87]

PR description:

This PR is mostly meant for clean up. No physics change expected.
It cleans up 2 things:

1. Phase2 EGM HLT moved from TICL V3 to V4 some time ago ([EGM HLT@Phase2] Move to TICL v4 #39820). But some remnants of TICL V3 had remained in EGM configs, which I did not notice before. Removing them now.
2. Removing the obsolete and unmaintainable config RecoEgamma/EgammaHLTProducers/python/HLTEgPhaseIITestSequence_cff.py. It was useful when it was introduced (in HGCal ID variables #32519), as it allowed to test Phase2 specific code which was being used only in HLT, which was otherwise not testable as the Phase2 HLT menu was not part of CMSSW at that time. Now that we have the Phase2 HLT menu in release, there is no point of having this additional Egamma Phase2 HLT config, which anyway became obsolete very quickly.

This pull request is fully signed and it will be integrated in one of the next master IBs (but tests are reportedly failing). 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)
