[openEuler-23.09] Introduce dynamic affinity for scheduler

【特性描述】

感知业务负载动态调整业务CPU亲和性，当业务负载低时使用prefered cpus处理，增强资源的局部性；当业务负载高时，
突破preferred cpus范围限制，通过增加cpu核的供给提高业务的QOS。

【特性竞争力】

dynamic affinity技术瞄准CPU资源利用率与CPU资源利用效率，当业务负载低时，在满足QOS的基础上，使用最少的CPU
资源，减少CPU迁移、idle切换、cache miss和跨numa访问，增强资源的局部性。当业务负载高时，又可以突破绑核约束
，使用更多CPU资源来提升QOS质量，提高CPU资源利用率。dynamic affinity对资源利用率、利用效率和系统功耗都有重
要的价值。

Hi barry19901226, welcome to the openEuler Community.
I'm the Bot here serving you. You can find the instructions on how to interact with me at Here.
If you have any questions, please contact the SIG: Kernel, and any of the maintainers.

1.测试接口的使用
2.测试低负载场景，检查是否只在preferrd cpus上运行
3.测试高负载场景，检查是否有线程运行在preferred cpus之外的其他有效cpu上。
