Following https://chromium-review.googlesource.com/c/v8/v8/+/3275554. Locally the binary size is increased by ~2.4mb (+2.9%) with a pretty significant speedup in startup:

                                                                                     confidence improvement accuracy (*)   (**)  (***)
misc/startup.js count=30 mode='process' script='benchmark/fixtures/require-builtins'        ***     12.28 %       ±1.13% ±1.52% ±2.00%
misc/startup.js count=30 mode='process' script='test/fixtures/semicolon'                    ***     17.39 %       ±1.12% ±1.50% ±1.97%
misc/startup.js count=30 mode='worker' script='benchmark/fixtures/require-builtins'         ***     14.54 %       ±0.77% ±1.03% ±1.35%

I think the increased binary size is worth it, but if we really worry about it, another (perhaps better) option would be to disable the built-in compression of V8 and compress the snapshot + source code + code cache ourselves using a different compression library (e.g. Deno switched to lz4 and zstd and got a pretty significant performance boost). I'd suggest to just disable it for now, regardless of whether we can follow up with a compression strategy that can reduce the binary size significantly without hurting performance, because currently a 2.9% binary size saving is not really worth the performance regression.

Maybe we could add a build option to enable it for those who want to optimize for size (along with existing build options that help reduce binary size)?

Rebased against #45746 to pull in better benchmarks and added the build option to enable the compression thanks to suggestion from @mscdex

Locally the size increase is now 2.4MB from the main branch, with the following benchmark numbers:

In the upstream, V8 also disables snapshot compression on the
desktop by default because the size reduction is not worth the
performance hit.
https://chromium-review.googlesource.com/c/v8/v8/+/3275554

Locally the binary size of Node.js is increased by ~2.7MB
(+3.2%) with a significant speedup in startup after snapshot
compression is disabled on macOS.

Also adds a --v8-enable-snapshot-compression to configure.py for
users who prefer a size reduction over speedup in startup.
Ideally we should implement our own compression for the source
code + the code cache + the snapshot instead of relying on V8's
builtin compression for just the snapshot.

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.

In the upstream, V8 also disables snapshot compression on the
desktop by default because the size reduction is not worth the
performance hit.
https://chromium-review.googlesource.com/c/v8/v8/+/3275554

Locally the binary size of Node.js is increased by ~2.7MB
(+3.2%) with a significant speedup in startup after snapshot
compression is disabled on macOS.

Also adds a --v8-enable-snapshot-compression to configure.py for
users who prefer a size reduction over speedup in startup.
Ideally we should implement our own compression for the source
code + the code cache + the snapshot instead of relying on V8's
builtin compression for just the snapshot.

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

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.

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.

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);
});
```

Is there any plan to enable snapshot compression with lz4 or zstd?
