The FileHandle class has many missing methods compared to node.
Add these.
## WHAT
- Add close method

Related issue: https://github.com/denoland/deno/issues/19358.
This is a regression that seems to have been introduced in
https://github.com/denoland/deno/pull/18905. It looks to have been a
performance optimization.
The issue is probably easiest described with some code:
```ts
const target = new EventTarget();
const event = new Event("foo");
target.addEventListener("foo", () => {
console.log('base');
target.addEventListener("foo", () => {
console.log('nested');
});
});
target.dispatchEvent(event);
```
Essentially, the second event listener is being attached while the `foo`
event is still being dispatched. It should then not fire that second
event listener, but Deno currently does.

Internally, `node-tap` spawns a child process with `stdio: [0, 1, 2]`.
Whilst we don't support passing fd numbers as an argument so far, it
turns out that `[0, 1, 2]` is equivalent to `"inherit"` which we already
support. See: https://nodejs.org/api/child_process.html#optionsstdio
Mapping it to `"inherit"` is fine for us and gets us one step closer in
getting `node-tap` working. I'm now at the stage where already the
coverage table is shown 🎉

## WHY

Node's fs/promises includes a FileHandle class, but deno does not. The
open function in Node's fs/promises returns a FileHandle, which provides
an IO interface to the file. However, deno's open function returns a
resource id.
### deno
```js
> const fs = await import("node:fs/promises");
undefined
> const file3 = await fs.open("./README.md");
undefined
> file3
3
> file3.read
undefined
Node:
```
### Node
```js
> const fs = await import("fs/promises");
undefined
> const file3 = await fs.open("./tests/e2e_unit/testdata/file.txt");
undefined
> file3
FileHandle {
_events: [Object: null prototype] {},
_eventsCount: 0,
_maxListeners: undefined,
close: [Function: close],
[Symbol(kCapture)]: false,
[Symbol(kHandle)]: FileHandle {},
[Symbol(kFd)]: 24,
[Symbol(kRefs)]: 1,
[Symbol(kClosePromise)]: null
}
> file3.read
[Function: read]
```
To be compatible with Node, deno's open function should also return a
FileHandle.
## WHAT
I have implemented the first step in adding a FileHandle.
- Changed the return value of the open function to a FileHandle object
- Implemented the readFile method in FileHandle
- Add test code
## What to do next
This PR is the first step in adding a FileHandle, and there are things
that should be done next.
- Add functionality equivalent to Node's FileHandle to FileHandle
(currently there is only readFile)

It's not used anymore. Subsequently allows removing
`ModuleMap::op_state`, allowing `ModuleMap` to have a sane default so
`JsRuntime::module_map` no longer needs to be optional.
For the first implementation of node:http2, we'll use the internal
version of `Deno.serve` which allows us to listen on a raw TCP
connection rather than a listener.
This is mostly a refactoring, and hooking up of `op_http_serve_on` that
was never previously exposed (but designed for this purpose).
This cleans up `JsRuntime` a bit more:
* We no longer print cargo's rerun-if-changed messages in `JsRuntime` --
those are printed elsewhere
* We no longer special case the OwnedIsolate for snapshots. Instead we
make use of an inner object that has the `Drop` impl and allows us to
`std::mem::forget` it if we need to extract the isolate for a snapshot
* The `snapshot` method is only available on `JsRuntimeForSnapshot`, not
`JsRuntime`.
* `OpState` construction is slightly cleaner, though I'd still like to
extract more

This PR adds the missing `process.reallyExit()` method to node's
`process` object.
Was [pinged on
twitter](https://twitter.com/biwanczuk/status/1663326659787862017)
regarding running the `fastify` test suite in node. They use `node-tap`
which has been around arguably the longest of the test frameworks and
relies on a couple of old APIs. They have `signal-exit` as a dependency
which in turn [makes use of
`process.reallyExit()`](8fa7fc9a9c/src/index.ts (L19)).
That function cannot be found anywhere in their documentation, but
exists at runtime. See
6a6b3c5402/lib/internal/bootstrap/node.js (L172)
This doesn't yet make `node-tap` work, but gets us one step closer.
Part of #17840
I haven't made any changes or additions to the tests themselves, just
moved the tests over and updated to match.

Rather than disallowing `ext:` resolution, clear the module map after
initializing extensions so extension modules are anonymized. This
operation is explicitly called in `deno_runtime`. Re-inject `node:`
specifiers into the module map after doing this.
Fixes #17717.
If a symlink within the `node_modules` directory lies outside that
directory, it will now warn and inline the file. For directories, it
will just warn for now.
Probably fixes #19251 (I'm still unable to reproduce).
This commit fixes problem with loading N-API modules that use
the "old" way of registration (using "napi_module_register" API).
The slot was not cleared after loading modules, causing subsequent
calls that use the new way of registration (using
"napi_register_module_v1" API) to try and load the previous module.

`isFile`, `isDirectory`, `isSymlink` are defined in `Deno.FileInfo`, but
`isBlockDevice`, `isCharacterDevice`, `isFIFO`, `isSocket` are not
defined.

This is what pnpm does and we were missing it. It makes modules work
which have a dependency on something, but don't say they have that
dependency, but that dep is still in the tree somewhere.
This commit fixes emitting "unhandledrejection" event when there are
"node:" or "npm:" imports.
Before this commit the Node "unhandledRejection" event was emitted
using a regular listener for Web "unhandledrejection" event. This
listener was installed before any user listener had a chance to be
installed which effectively prevent emitting "unhandledrejection"
events to user code.
Closes https://github.com/denoland/deno/issues/16928
When someone explicitly opts into using the node_modules dir via
`--node-modules-dir` or setting `"nodeModulesDir": true` in the
deno.json file, we should eagerly ensure a top level package.json
install is done on startup. This was initially always done when we added
package.json support and a package.json was auto-discovered, but scaled
it back to be lazily done when a bare specifier matched an entry in the
package.json because of how disruptive it was for people using Deno
scripts in Node projects. That said, it does not make sense for someone
to opt-into having deno control and use their node_modules directory and
not want a package.json install to occur. If such a rare scenario
exists, the `DENO_NO_PACKAGE_JSON=1` environment variable can be set.
Ideally, we would only ever use a node_modules directory with this
explicit opt-in so everything is very clear, but we still have this
automatic scenario when there's a package.json in order to make more
node projects work out of the box.
