Jordan Borean e972287c35 win_exec: refactor PS exec runner (#45334)
* win_exec: refactor PS exec runner

* more changes for PSCore compatibility

* made some changes based on the recent review

* split up module exec scripts for smaller payload

* removed C# module support to focus on just error msg improvement

* cleaned up c# test classifier code
