Add java_genrules to use jars as inputs and outputs
Add a java_genrule that has the right multilib flags to be a
dependency of a java rule. Make java libraries implement
SourceFileProducer so that their classes jar can be used as an
input to a java_genrule. Allow libs and static_libs dependencies
to be a java_genrule.
Test: TestJarGenrules
