Convert the otatools.zip to soong for jars, cert files and releasetools

- Use "otatools_package_cert_files" to find cert files.
- The jar modules is from $(INTERNAL_OTATOOLS_MODULES_WITH_DEPS).
- The "otatools-package-temp" is temporary. It will be changed as
  "otatools-package" after all files are ready in soong.
