EN:
Observability task, optimizing thread pool index embedding function
1 Need to specify a name for the core thread pool
2 Core thread pool index is not effective
3. Remove the frame-level indicators and only keep the core monitoring indicators (the frame-level code type is completely deleted and will be considered later)

可观测性任务，优化线程池指标埋点功能
1需要为核心线程池指定名称
2核心线程池指标生效问题
3移除框架层指标只保留核心监控指标
