RFR: 8321156: Improve the handling of invalid UTF-8 byte sequences for ZipInputStream::getNextEntry and ZipFile::getComment

[Lance Andersen]

Please review this PR which addresses the handling of invalid UTF-8 byte sequences in the entry name of a LOC file header and a Zip file comment which is returned via ZipFile::getComment.

As part of the change, `ZipFile::getComment` will now return `null` if an invalid UTF-8 byte sequence is encountered while converting the byte array to a String.  The CSR for this change has also been approved.

Mach5 tiers 1-3 are clean with this change.
