Make the OMERO.server autostart on Windows (see #11448)

To be consistent with the docs, the server service installed by ``bin\omero admin start`` should be configured initially to automatic startup mode. This PR updates the call to the Windows service manager API.

To test, deploy OMERO.server on Windows and verify that the ``OMERO.server`` service has the startup mode as "Automatic".

This will have to be rebased to ``develop``.
