Include only Java classes in zip archive of generated files

Summary:
Changelog:
[General] [Changed] - Include only Java classes in zip archive of generated files for JS codegen

This diff adds one more Buck rule to copy only Java files to a temporary dir, so that the zip_rule will only package the Java classes and skip C++ files. It makes the generated code more organized and decreases the time to create the ZIP-archive.
