Build android_icu4j_resources into a standalone static lib

- In the downstream branch master-icu-dev, the resource files are generated.
  To include all the generated resources in libart and core-all, the
  generated resources need to be in a single jar.
- No java files included in the static lib. There should be no circular
  dependency. Verified
  out/target/product/generic_x86/obj/JAVA_LIBRARIES/android_icu4j_resources_lib_intermediates/javalib.jar
  has no .java/.class files.
