RFR: 8340684: Reading from an input stream backed by a closed ZipFile has no test coverage

Please review this PR which adds test coverage for the case of reading from an input stream obtained using`ZipFile:getInputStream` after the backing `ZipFile` has been closed. 

The unspecified but long-standing behavior for this unusual use case is to throw `IOException`, but this is not verified by current tests. Adding a test would help prevent regressions in this area.

The test is parameterized to excercise a variation of stored/deflated entries, and a variation of read behaviors before the `ZipFile` is closed.
