Added a test to verify mariadb-upgrade-service functionality on Windows.
The test runs mariadb-install-db.exe to create a Windows service, then
executes mariadb-upgrade-service.exe while the service is online
or offline.
There is no real cross-version upgrade in this test(not possible with
MTR), the actual goal is just to run smoke-test.
Last times mariadb-upgrade-service was broken (CONC-760, MDEV-30639)
there were problems with named pipe connections, which could be detected
and prevented by smoke-test alone.
