New candidate JEP: 336: Deprecate the Pack200 Tools and API

[Daniel Megert]

pack200 is used by the Eclipse update manager a.k.a. p2. The JARed 
plug-ins are compressed with pack200 and put into a p2 repository. 
Removing pack200 will make the download (and hence install) of plug-ins 
much slower. Eclipse would therefore like to keep this technology. If 
that's not an option, then we would like that the removal does not happen 
before Java 13.
