Adds a fast path for UTF8. I'll remove my local benchmark and share the Benchmark CI result asap.

Fixes nodejs/performance#3

Benchmark CI: https://ci.nodejs.org/view/Node.js%20benchmark/job/benchmark-node-micro-benchmarks/1219/

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case, there are 54 comparisons, you can thus
expect the following amount of false-positive results:
  2.70 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.54 false positives, when considering a   1% risk acceptance (**, ***),
  0.05 false positives, when considering a 0.1% risk acceptance (***)

LGTM if CI is green. (It's unclear to me if this will break tests or anything when compiled --without-intl but Jenkins CI will check that.)

It calls strncmp on data but is data null terminated? That's potentially an out-of-bounds read (into uninitialized bytes in ArrayBufferViewContents::stack_storage_), and then an overflow on length if it happens to match. ASan would only catch this when length overflows.

fs.watch recursive support on Linux:

`fs.watch` supports recursive watch using the `recursive: true` option.

```js
const watcher = fs.watch(testDirectory, { recursive: true });
watcher.on('change', function(event, filename) {
});
```

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);

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`

the last time the file was modified in ms, and `name`, the name of the file.

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);
});
```

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.
