Review Request: 8004281: build-infra: Move all jar creation to images target and put jars in images/lib

[Erik Joelsson]

This patch moves all jar file creation in jdk (except demos) to 
CreateJars.gmk, which is called by the images target. All the jar files 
are put in images/lib instead of being spread between jdk/lib and 
images/lib. This makes images creation simpler since all jar files can 
be found in one place.
