JavaScript: Add support for import() syntax from ECMAScript 2020 (dynamic import) #23083

Description of the issue

CodeQL doesn't appear to support the dynamic import (import()) feature from ECMAScript 2020.

In this example, taint doesn't flow through the await import:

export const run = async (request) => {
  const { handle } = await import("./handle.js");
  return handle(request);
};
