Apply memory profiling parameters during mutate/merge operations

Why it matters

This feature helps users understand and analyze memory consumption patterns during data mutations and merges, enabling better memory management, troubleshooting, and optimization of heavy operations in ClickHouse.

How to use it

Users can enable memory profiling by configuring the settings max_untracked_memory, memory_profiler_step, and memory_profiler_sample_probability in their server configuration or session. These parameters control the threshold of untracked memory, the profiling granularity, and the sampling probability, respectively.
