RFR JDK-8187485: Update Zip implementation to use Cleaner, not finalizers

[Roger Riggs]

Hi Sherman,

Looking good.

Deflater(573) and Inflater(398), and ZipFile(890):
    For consistency, where is says "phantom-reachable" in the finalize 
methods it can say "unreachable".

ZStreamRef:
  - line 92: FinalizableZStreamRef  - owner should be final

Regards,  Roger
