CL 244958 includes isWindowsService function that determines if a process is running as a service. The code of the function is based on public .Net implementation. IsAnInteractiveSession function implements similar functionality, but is based on an old Stackoverflow post., which is not as authoritative as code written by Microsoft for their official product. This change copies CL 244958 isWindowsService function into svc package and makes it public. The intention is that future users will prefer IsWindowsService to IsAnInteractiveSession. Also this change adds "Deprecated" comment to IsAnInteractiveSession to point future users to IsWindowsService. Call to IsAnInteractiveSession is also replaced with IsWindowsService in golang.org/x/sys/windows/svc/example package.
