Merge InputTypeStrategy and InputTypeValidator

      Description

      Due to the design of Calcite, even operand checkers that were originally used for "checking" can infer and modify call arguments nowadays. This conflicts with our original design of separating validation and input type inference. Therefore, we propose to merge those two concepts in Flink into one `InputTypeStrategy` that is responsible for both inferring/enriching and validation.
