Remove MemoryTrackingInBackground* Metrics to Prevent Misleading Results

Remove MemoryTrackingInBackground* metrics to avoid potentially misleading results. This fixes #15684. #15813 (alexey-milovidov).
Removed MemoryTrackingInBackground* metrics from ClickHouse to prevent potentially misleading memory tracking results.

Why it matters

The MemoryTrackingInBackground* metrics were found to produce inaccurate or misleading memory usage information. Removing them improves the accuracy and reliability of memory tracking diagnostics, helping users better understand the real memory consumption of their ClickHouse server.

How to use it

No action is required from users. The MemoryTrackingInBackground* metrics have been removed automatically in the new version, resulting in improved memory tracking behavior out of the box.
