RFR: 8304014: Convert test/jdk/java/util/zip/ZipFile/CorruptedZipFiles.java to testNG

[Eirik Bjorsnos]

CorruptedZipFiles could benefit from some spring cleaning and a conversion to testNG:

- 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 `expectThrows`
- A bunch of constants copied over from `ZipFile` can be deleted since JDK-6225935 has long been fixed

-------------

Commit messages:
 - Merge branch 'master' into corrupted-zip-files-ng
 - Give the @BeforeMethod and @AfterMethod more meaningful names
 - Improve comments and method names to help future maintainers understand what these tests verify.
 - Merge branch 'master' into corrupted-zip-files-ng
 - Trim whitespace and fix some spelling
 - Convert test CorruptedZipFiles to testNG and delete ZipFile constants copies which are now obsolete.
