2023-01-05, Version 18.13.0 'Hydrogen' (LTS)

Notable changes:

Add support for externally shared js builtins:

By default Node.js is built so that all dependencies are bundled into the
Node.js binary itself. Some Node.js distributions prefer to manage dependencies
externally. There are existing build options that allow dependencies with
native code to be externalized. This commit adds additional options so that
dependencies with JavaScript code (including WASM) can also be externalized.
This addition does not affect binaries shipped by the Node.js project but
will allow other distributions to externalize additional dependencies when
needed.

Introduce `File`:

The File class is part of the [FileAPI](https://w3c.github.io/FileAPI/).
It can be used anywhere a Blob can, for example in `URL.createObjectURL`
and `FormData`. It contains two properties that Blobs do not have: `lastModified`,
the last time the file was modified in ms, and `name`, the name of the file.

Contributed by Khafra in #45139

Support function mocking on Node.js test runner:

The `node:test` module supports mocking during testing via a top-level `mock`
object.

```js
test('spies on an object method', (t) => {
  const number = {
    value: 5,
    add(a) {
      return this.value + a;
    },
  };
  t.mock.method(number, 'add');

  assert.strictEqual(number.add(3), 8);
  assert.strictEqual(number.add.mock.calls.length, 1);
});
```
