Fix MSan Report for range Function with UInt256 Argument

Official CH changelog text
Fix MSan report for function range with UInt256 argument (support for large integers is experimental). This closes #22157. #22387 (alexey-milovidov).
Fixed a MemorySanitizer (MSan) report in the range function when used with UInt256 arguments, improving support for large integers in ClickHouse.

Why it matters

This fix addresses an MSan issue that occurred when the range function was called with UInt256 type arguments. By resolving this, it enhances the experimental support for large integer operations in ClickHouse, ensuring more reliable and correct behavior when working with 256-bit unsigned integers.

How to use it

Users can benefit from this fix when using the range function with UInt256 type values without any additional configuration, as it is an internal bug fix improving the existing experimental feature.
