Add tupleConcat function, closes #52759, PR #53239

Why it matters

This feature introduces the tupleConcat function to enable users to concatenate multiple tuples into a single tuple. It addresses the need for seamless tuple merging, simplifying operations that require combining tuple elements and enhancing query expressiveness.

How to use it

Use the tupleConcat function by passing the tuples you want to concatenate as arguments. For example:

SELECT tupleConcat(tuple(1, 2), tuple(3, 4))

This returns a single tuple with elements from both tuples.
