Add introspection

Async logging: Make limits tuneable and add introspection. #85105 (Raúl Marín).
Introduces tunable limits and introspection capabilities for asynchronous logging in ClickHouse.

Why it matters

This feature allows users to configure limits for asynchronous logging, improving control over logging behavior and resource usage. Additionally, introspection enables monitoring and debugging of async logging internals, enhancing observability and management of logs.

How to use it

Users can adjust the limits for async logging through configuration settings and utilize new introspection tools or queries to inspect the internal state and metrics of asynchronous logs.
