merge 5.7 P_S memory instrumentation and tables

Details

    Description

      merge 5.7 P_S memory instrumentation and tables

      perhaps we can get rid of MY_THREAD_SPECIFIC and deduce this from the P_S key?

            This would be good for compatibility with MySQL but also because "memory issues do occur" and in the past it has been very hard to determine where the memory was going and thus find the cause.

            Bumped into a memory issue in 10.3.13 where this would have been useful for tracing the issue.

            @Simon Mudd Can you specify what kind of memory issue you had experienced with 10.3.13? Were you able to fix it by a configuration change or did you do a minor/major upgrade to resolve it?
