`ModuleInfoWriter` is not used by the runtime. Move it to the test library as `jdk.test.lib.util.ModuleInfoWriter`. The tests are updated to use the test library instead. `ModuleInfoWriter` depends on `jdk.internal.module` types and the Classfile API. Hence `@modules java.base/jdk.internal.classfile` and other classfile subpackages are added.
