Enhancement

Continuous profiling does not provide a good experience in TiDB; it lacks stack search capabilities and is not convenient for examining profiles over extended periods. It also does not support visualization for goroutines. Here, we can leverage the infrastructure of Pyroscope to implement this system, which will be far more reliable than what we have developed on our own.
