Add ability to Share Native Object Instances between Main and Worker Runtimes

Both Worker and Main JS runtime instances use the same Java environment hence the native objects can be shared between the two.
Main:

const nativeObject = new java.lang.String("string");
const worker = new Worker(...);
worker.postMessage({
  myNativeString: globalThis.createNativeHandle(nativeObject)
});

Worker:

globalThis.onmessage = (message) => {
  const nativeObject = globalThis.resolveNativeHandle(message.myNativeString);
}

未指定文件或测试。首先跟踪所示 createNativeHandle 和 resolveNativeHandle 入口点周围 Main 与 Worker 的运行时消息路径，然后确定 Java-backed 对象如何在不同运行时之间保持有效。完成的标准是示例可以将 native String 从 Main 发送到 Worker，并在那里安全地解析它。
