This change makes the csx files in the performance tool to use new ninary helper rather than use the helpers in csx
Advantages:
1. Type unification - types used in different compilation across the csx runs can unified. No need to use dynamic
2. With more helper code in CS project we get the goodness of language services when working with these files
3. With various entry points to the scripts, it is tough to understand what variables are set at various stages of the run

Also when #load a csx, I have added a comment to mention why we are `#load`ing the csx. This is easy to track when the code gets refactored and removing stale code
