### Describe the bug When [translating a substrait scalar function call](https://github.com/fmonjalet/datafusion/blob/b7060c143c3eede8f49f8b51d92e184043e3a081/datafusion/substrait/src/logical_plan/consumer/expr/scalar_function.rs#L25) to DataFusion logical plan, when the function name [translates to a binary operator](https://github.com/fmonjalet/datafusion/blob/b7060c143c3eede8f49f8b51d92e184043e3a081/datafusion/substrait/src/logical_plan/consumer/expr/scalar_function.rs#L78) and has a large number of arguments (say 2000), further processing of this logical plan result in stack overflow. ### To Reproduce [This commit](https://github.com/apache/datafusion/commit/fd13db09dd76ea888f7dc43340a4b3b7a316f038) contains a reproducer plan and test. The plan is pretty large (because a lot of arguments are required to see the stack overflow), but pretty simple: it's an `OR(col == a, col ==b, col == c, ..., col == x)`. We could argue that this precise example should actually be a substrait `SingularOrList`, but the issue can be triggered all the same with other operators and expressions. ### Expected behavior No stack overflow or crash. At best, the plan is accepted and executed, at worst DataFusion returns a clean error. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
