[windows] create powershell modules cache permanently 
PSModuleAnalysisCachePath points to modules analysis cache. By default
it is stored in user profile. We create user every time, and module
analysis cache rebuild takes ~20s.

by storing cache in permanent location, initial powershell startup
takes ~8s instead of ~20s
