RFR: 8314891: Additional Zip64 extra header validation

[Lance Andersen]

Please review this PR which improves the Zip64 extra header validation:

- Throw a ZipException If the extra len field is 0 and :
-- size, csize, or loc offset are not set to 0xFFFFFFFF
-- disk starting number is not set to 0xFFFF

- We have a valid size for the Zip64 extra header but we are missing the csize or loc fields if they are expected to be part of the header

Mach5 tiers 1-3 are clean
