This PR enables reproducible Jars, Jmods and openjdk image zip files (eg.src.zip). It provides support for SOURCE_DATE_EPOCH for Jar, Jmod and underlying ZipOutputStream's. It fixes the following keys issues relating to reproducibility: - Jar and ZipOutputStream are not SOURCE_DATE_EPOCH aware - Jar and ZipOutputStream now detect SOURCE_DATE_EPOCH environment setting - Jar and Jmod file content ordering was non-determinsitic - Fixes to Jar and Jmod main's to ensure sorted classes content ordering - openjdk image zip file generation used "zip" which is non-determinsitic - New openjdk build tool "GenerateZip" which produces the final determinsitic zip files as part of the build and also detects SOURCE_DATE_EPOCH
