Updated AWS C++ SDK for Global Regions in S3

Updated AWS C++ SDK in order to utilize global regions in S3. #17870 (Vladimir Chebotarev).
Updated the AWS C++ SDK used by ClickHouse to support global regions in Amazon S3.

Why it matters

This update enables ClickHouse to interact with S3 buckets located in global AWS regions, enhancing compatibility and allowing users to access data stored across a wider range of AWS locations.

How to use it

No user action required; the update is integrated by default in ClickHouse. Users can continue accessing S3 storage normally, now with support for global regions.
