Enable trace_log

Why it matters

This feature addresses the problem of trace logs being less human-readable in older ClickHouse versions by enabling symbolization by default. It helps users more easily interpret trace logs for debugging and performance analysis without manual configuration.

How to use it

Users do not need to perform any manual action as trace_log.symbolize is enabled by default for old deployments. For other cases, users can control this setting via the trace_log.symbolize parameter in their configuration.
