Client to Display Server-Side Elapsed Time for ClickHouse Performance Comparison

Official CH changelog text
The client will show server-side elapsed time. This is important for the performance comparison of ClickHouse services in remote datacenters. This closes #38070. See also this for motivation. #39968 (Alexey Milovidov).
The ClickHouse client now displays server-side elapsed time, providing precise measurement of query execution duration as measured by the server.

Why it matters

This feature addresses the need to accurately compare performance of ClickHouse services, especially in remote datacenter setups, by showing the actual time spent on the server rather than client-side timings which can be affected by network latency.

How to use it

Users will automatically see the server-side elapsed time in the client output when running queries; no additional configuration is required.
