From user's perspective, when the library is specified, the function can be registered correctly. These two functions are placed in two distinct slots.

In `SqlLibraryOperators`, We'd better seperate the `CONCAT_FUNCTION` into `CONCAT_FUNCTION` and `ORACLE_CONCAT_FUNCTION`. For `ORACLE_CONCAT_FUNCTION`, we can use `SqlOperandCountRanges.of(2)` to enable the constraint. (2)Implement the `CONCAT_FUNCTION` in SqlFunctions and register the implementation in `RexImpTable`. (3)Update the unparse logic accordingly. This is an automated message from the Apache Git Service.
