Make BasePath::new_temp_dir return the same path for the program lifetime (#12246)

* Make `BasePath::new_temp_dir` return the same path for the program lifetime

Instead of returning always a different path, this now returns the same path for the entire lifetime
of the program. We still ensure that the path is cleared at the end of the program.
