Since we skipped trivial constraint with `Any?` from parameter type of function `equals`, the compiler thought that there is no proper constraints (upper bounds do not matter here) and marked resolved call as a failed one, then diagnostic about missing equals was added Also, tune `TrivialConstraintTypeInferenceOracle` for `Any?`-like constraints #KT-30724 Fixed
