This is an automated cherry-pick of #57403

What problem does this PR solve?

Issue Number: close #55886

Problem Summary:

What changed and how does it work?

  1. Both evaluateExprWithNull and evaluateExprWithNullInNullRejectCheck use NewFunction instead of NewFunctionInternal to create a scalar function
  2. let EvaluateExprWithNull return error if some error happens inside EvaluateExprWithNull
  3. The caller of EvaluateExprWithNull need to decide how to handle this error, currently, all the callers of EvaluateExprWithNull are optimizer, and will ignore the error
