InstallScript Functions ServiceExistsService and ServiceGetServiceState No Longer Require Elevated Privileges

The InstallScript functions ServiceExistsService and ServiceGetServiceState no longer require elevated privileges. Therefore, installations can now call these functions when end users have limited privileges, such as in the Install UI sequence of a Basic MSI installation.

This enhancement resolves issue IOC-000059857.
