Fix nullability report for spark expression

[hsiang-c]

Describe the bug

As apache/datafusion#19144 indicates, most of DF's Spark expression do not report the nullability correctly.

Spark 4.0 has a nullIntolerant method defined in Expression and the comment is

  /**
   * When an expression inherits this, meaning the expression is null intolerant (i.e. any null
   * input will result in null output). We will use this information during constructing IsNotNull
   * constraints.
   */

I think Comet should have similar fix.
