[Scripting] Support native URL and URLSearchParams

[NghiaTranUIT]

Description

Some users complain that this script can't work:

async function onRequest(context, url, request) {
  console.log(url);

  const urlItem = new URL("https://example.com?foo=1&bar=2");
  const params1 = new URLSearchParams(urlItem.search);

  // Done
  return request;
}

and get the following error:

Error: ReferenceError: Can't find variable: URL
Error: ReferenceError: Can't find variable: URLSearchParams

The problem is:

• URL and URLSearchParams are not natively supported by JavascriptCore framework.

Why this feature/change is important?

• Can use URL and URLSearchParams
• Easier to deconstruct the URL and handle the Search Param.
