Optimize Read Buffer for PARTIALLY_DOWNLOADED File Segment

optimize file segment PARTIALLY_DOWNLOADED get read buffer. #37338 (xiedeyantu).
Optimize reading buffers for partially downloaded file segments in ClickHouse.

Why it matters

This feature improves the efficiency of reading partially downloaded file segments by optimizing the buffer usage. It reduces unnecessary data fetches and enhances performance during segment reads, leading to faster query execution and better resource utilization.

How to use it

The optimization is applied automatically when ClickHouse reads partially downloaded file segments. Users do not need to enable any specific settings; the improvement is integrated into the internal file segment reading process.
