Abort Multipart Upload if No Data Written to S3

Abort multipart upload if no data was written to S3. #16840 (Pavel Kovalenko).
Abort multipart upload to S3 if no data was written during the upload process.

Why it matters

Prevent incomplete or empty multipart uploads to S3 storage by automatically aborting the upload when no data has been written. This improves storage efficiency and avoids unnecessary storage costs by cleaning up empty uploads.

How to use it

This behavior is applied automatically when performing multipart uploads to S3 in ClickHouse. Users do not need to enable anything explicitly; multipart uploads with no written data will be aborted to maintain storage hygiene.
