This patch adds snapshot support to single executable applications.
To build a snapshot from the main script when preparing the
blob that will be injected into the single executable application,
add `"useSnapshot": true` to the configuration passed to
`--experimental-sea-config`. For example:
```
{
"main": "snapshot.js",
"output": "sea-prep.blob",
"useSnapshot": true
}
```
The main script used to build the snapshot must invoke
`v8.startupSnapshot.setDeserializeMainFunction()` to configure the
entry point. The generated startup snapshot would be part of the
preparation blob and get injected into the final executable.
When the single executable application is launched, instead of running
the `main` script from scratch, Node.js would instead deserialize the
snapshot to get to the state initialized during build-time directly.

Windows where command lists all places it finds a pattern in Path.
The first one is the one that executes when called.
So the old code was overriding the first executable by any other match.

The recent Postject upgrade, https://github.com/nodejs/node/pull/48072,
included a performance improvement for the injection operation
(see https://github.com/nodejs/postject/pull/86), so now it might be
possible to run the SEA tests on the ppc64 architecture runners on
Jenkins, which was previously getting timed out.

We had a few code snippets that were using a non-descriptive tag (e.g.
`console` or `text`), whereas the actual language it's using describes
it better, and improves the syntax highlighting. This commit also
removes non-necessary leading chars (e.g. `$`, `>`, or `%`) to make it
easier for readers to copy and paste to try the command themselves.
