Description

Replace temporary directory functionality of GenericTestUtils with JUnit's @TempDir. The latter is automatically cleaned up.

• Usage of File getRandomizedTestDir(), File getTestDir(), and File getTestDir(String) can be directly replaced by @TempDir. If the temp directory is stored in a local variable, convert it to a field for it.
• For usages of String getRandomizedTempPath() and String getTempPath(String) we still need to add a Path or File as a field, and use toString() where needed.
• Post-test deletion of the dir can be removed.
• If @BeforeEach and @AfterEach methods are only used to create/delete the dir, they can be deleted as well.
• Any unused imports should be removed.
