Complete rewrite of Windows exec wrapper (#21510)

* supports pipelining for faster execution
* supports become (runas), creates interactive subsession under WinRM batch logon
* supports usage of arbitrary module_utils files
* modular exec wrapper payload supports easier extension
* integrates async wrapper behavior for pipelined/become'd async
* module_utils are loaded as true Powershell modules, no more runtime modifications to module code
