Description

Currently we do not validate the argument count in TypeInferenceOperandInference which results in bugs like e.g. FLINK-33248. We do run the check already in TypeInferenceUtil when running inference for Table API so we should do the same in TypeInferenceOperandInference case.

We could expose TypeInferenceUtil#validateArgumentCount and call it. If the check fails, we should not adapt operandTypes
