What I did
Add a new orchstats class and background thread for orchagent task statistics.
Why I did it
The original record, swss.rec, will take too much CPU and disk space in the scenario of a huge entry scale. So, a flyweight statistic method is needed for monitoring the performance of orchagent.
How I verified it
The SWSS Azp should pass and the PR: sonic-net/sonic-mgmt#8505 provides a script for profiling orchagent.
