RFR: 8265152: jpackage cleanup fails on Windows with IOException deleting msi

[Yasumasa Suenaga]

When creating an "exe" installer on Windows, `AbstractBundler.cleanup()` calls `IOUtils.deleteRecursive()` to delete the tmp directory. It can intermittently fail trying to delete the msi file.

[JDK-8263135](https://bugs.openjdk.java.net/browse/JDK-8263135) removed `unique_ptr` from jpackage sources due to compiler warnings in VS 2019 (16.9.0), so we need to release the resource manually. However `DatabaseView` didn't do that.
