Support Lambda Argument in APPLY Column Transformer for Multi-Argument Functions

Support lambda argument for APPLY column transformer which allows applying functions with more than one argument. This is for #27877. #27901 (Amos Bird).
Support for lambda arguments in the <code>APPLY</code> column transformer enabling functions with multiple arguments.

Why it matters

This feature enhances the <code>APPLY</code> column transformer by allowing users to apply functions that accept more than one argument. It solves the limitation of applying only single-argument functions, providing greater flexibility and expressiveness in column transformations.

How to use it

Users can now define lambda functions with multiple parameters within the <code>APPLY</code> transformer to transform columns. For example, using <code>APPLY</code> with a lambda taking two or more arguments to perform complex operations on columns.
