Remove EGCrackVetoCleaningTool and related DFCommonCrackVetoCleaning variable

EGamma reconstruction contained a bug for mc16a, which was subsequently fixed before the submission of mc16d. To correct the bug in mc16a, JB added the EGCrackVetoCleaningTool that runs at derivation level and which flags e/y objects affected by the bug with the DFCommonCrackVetoCleaning. Since the bug in EGamma reco has been corrected long ago (https://gitlab.cern.ch/atlas/athenaprivate1/-/merge_requests/7195) and it is still in place (egammaSuperClusterBuilderBase.cxx#L418) we can remove this derivation-level correction.

I do expect a change in output since I remove a variable.
