Delete Hibernate ORM's unzipped SQL files on shutdown

[yrodiere]

Description

See extensions/hibernate-orm/runtime/src/main/java/io/quarkus/hibernate/orm/runtime/SchemaToolingUtil.java after #47338 is merged: a temporary directory is created but never deleted.

Implementation ideas

We need some changes to the code to remember which directories we created.

Then we need to delete the directory ASAP. I think "after startup" would be fine. Maybe we should also ensure it's deleted on startup failure, though...
