RFR: 8304014: Convert test/jdk/java/util/zip/ZipFile/CorruptedZipFiles.java to junit [v6]

[Eirik Bjorsnos]

> CorruptedZipFiles could benefit from some spring cleaning and a conversion to junit:
> 
> - The actual tests are moved into their own `@Test` methods, given more meaningful names and a Javadoc comment explaining the constraint being verified
> - The setup code is moved to a `@Before` method, slightly modernized and rewritten to take advantage of `assertEquals` 
> - `checkZipExceptionImpl` is updated to take advantage of `assertThrows`
> - A bunch of constants copied over from `ZipFile` can be deleted since JDK-6225935 has long been fixed
