[~MasseGuillaume], nice work. I have revised a little; see [julianhyde/5624-spark-array|https://github.com/julianhyde/calcite/tree/5624-spark-array]. If this looks good, I'll merge to main.

> The following query is valid in Apache Spark.
> {code:java}
> spark-shell
> scala> spark.sql("""select array(1, 2, 3)""")
> res1: org.apache.spark.sql.DataFrame = [array(1, 2, 3): array<int>]{code}
> However, it would fail to parse in Apache Calcite
>  
> AtomicRowExpression should not have ArrayConstructor for Apache Spark. Arrays are constructed by calling the array function ([https://spark.apache.org/docs/latest/api/sql/index.html#array]).
>  
> {code:java}
> array()
> array(1)
> array(1, 2, 3){code}
