73ed606bf6 feat(unstable): Improve FFI types (#20215)
Few improvements to FFI types:
1. Export `PointerObject` for convenience. It's fairly commonly used in
library code and thus should be exported.
2. Fix various comments around `PointerValue` and `UnsafePointer` and
expand upon them to better reflect reality.
3. Instead of using a `Record<"value", type>[T]` for determining the
type of an FFI symbol parameter use direct `T extends "value" ? type :
never` comparison.

The last part enables smuggling extra information into the parameter and
return value string declarations at the type level. eg. Instead of just
`"u8"` the parameter can be `"u8" & { [brand]: T }` for some `T extends
number`. That `T` can then be extracted from the parameter to form the
TypeScript function's parameter or return value type. Essentially, this
enables type-safe FFI!

The foremost use-cases for this are enums and pointer safety. These are
implemented in the second commit which should enable, in a backwards
compatible way, for pointer parameters to declare what sort of pointer
they mean, functions to declare what the API definition of the native
function is, and for numbers to declare what Enum they stand for (if
any).

b8448e30dc fix(ext/http): ensure request body resource lives as long as response is alive (#20206)
Deno.serve's fast streaming implementation was not keeping the request
body resource ID alive. We were taking the `Rc<Resource>` from the
resource table during the response, so a hairpin duplex response that
fed back the request body would work.

However, if any JS code attempted to read from the request body (which
requires the resource ID to be valid), the response would fail with a
difficult-to-diagnose "EOF" error.

This was affecting more complex duplex uses of `Deno.fetch` (though as
far as I can tell was unreported).

Simple test:

```ts
        const reader = request.body.getReader();
        return new Response(
          new ReadableStream({
            async pull(controller) {
              const { done, value } = await reader.read();
              if (done) {
                controller.close();
              } else {
                controller.enqueue(value);
              }
            },
          }),
```

And then attempt to use the stream in duplex mode:

```ts

async function testDuplex(
  reader: ReadableStreamDefaultReader<Uint8Array>,
  writable: WritableStreamDefaultWriter<Uint8Array>,
) {
  await writable.write(new Uint8Array([1]));
  const chunk1 = await reader.read();
  assert(!chunk1.done);
  assertEquals(chunk1.value, new Uint8Array([1]));
  await writable.write(new Uint8Array([2]));
  const chunk2 = await reader.read();
  assert(!chunk2.done);
  assertEquals(chunk2.value, new Uint8Array([2]));
  await writable.close();
  const chunk3 = await reader.read();
  assert(chunk3.done);
}
```

In older versions of Deno, this would just lock up. I believe after
23ff0e722e, it started throwing a more
explicit error:

```
httpServerStreamDuplexJavascript => ./cli/tests/unit/serve_test.ts:1339:6
error: TypeError: request or response body error: error reading a body from connection: Connection reset by peer (os error 54)

Some people might get think they need to import from this directory,
which could cause confusion and duplicate dependencies. Additionally,
the `vendor` directory has special behaviour in the language server, so
importing from the folder will definitely cause confusion and issues

375bf08ce2 feat(ext/web): resourceForReadableStream (#20180)
Extracted from fast streams work.

This is a resource wrapper for `ReadableStream`, allowing us to treat
all `ReadableStream` instances as resources, and remove special paths in
both `fetch` and `serve`.

Performance with a ReadableStream response yields ~18% improvement:

```
  return new Response(new ReadableStream({
    start(controller) {
      controller.enqueue(new Uint8Array([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]));
      controller.close();
    }
  })
```

3552ba378b perf(ext/event): optimize Event constructor (#20181)
This PR optimizes `Event` constructor

- ~Added a fast path for empty `eventInitDict`~ Removed `EventInit`
dictionary converter
- Don't make `isTrusted` a
[LegacyUnforgeable](https://webidl.spec.whatwg.org/#LegacyUnforgeable)
property. Doing so makes it non-spec compliant but calling
`Object/Reflect.defineProperty` on the constructor is a big bottleneck.
Node did the same a few months ago
https://github.com/nodejs/node/pull/46974. In my opinion, the
performance gains are worth deviating from the spec for a
browser-related property.

This PR optimizes `URLPattern.exec` 

- Use component keys from constructor instead of calling it on every
`.exec`. AFAIK keys should always be
`protocol`,`username`,`password`,`hostname`,`port`,`pathname`,`search`,`hash`.
Haven't looked much into it but I think it's safe to define these
outside the constructor as well.
- Add a fast path for `/^$/u` (default regexp) and empty input
- Replaced `ArrayPrototypeMap` & `ObjectFromEntries` with a `for` loop.

f1a2d928cb feat(ext/node): eagerly bootstrap node (#20153)
To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:

 - [x] Process stdin/stdout/stderr are lazily created
 - [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

a8a7848c86 perf(ext/node): optimize http headers (#20163)
This PR optimizes Node's `IncomingMessageForServer.headers` by replacing
`Object.fromEntries()` with a loop and `headers.entries` with
`headersEntries` which returns the internal array directly instead of an
iterator

## Benchmarks

Using `wrk` with 5 headers

```
wrk -d 10s --latency -H "X-Deno: true" -H "Accept: application/json" -H "X-Foo: bar" -H "User-Agent: wrk" -H "Accept-Encoding: gzip, br" http://127.0.0.1:3000

9f761fa2cd fix(ext/net): implement a graceful error on an invalid SSL certificate (#20157)
The goal of this PR is to address issue #19520 where Deno panics when
encountering an invalid SSL certificate.

This PR achieves that goal by removing an `.expect()` statement and
implementing a match statement on `tsl_config` (found in
[/ext/net/ops_tsl.rs](e071382768/ext/net/ops_tls.rs (L1058)))
to check whether the desired configuration is valid

29a34757eb fix(cli) error gracefully when script arg is not present and --v8-flags is present in deno run (#20145)
Fix #20022, fix #19627 (duplicate)

#17333 upgraded clap from version 3.1 to version 4. clap version 3.2.0
(intentionally) broke a behavior that deno was relying on to make `deno
run --v8-flags=--help` work without specifying a file, see
clap-rs/clap#3793. The workaround was to make the script argument
required _unless_ `--v8-flags` is present. This broke the expectation
that all successfully parsed `run` commands have the script argument
set, leading to the panic on
`matches.remove_many::<String>("script_arg").unwrap()`.

Clap, as far as I was able to find out, does not currently offer a neat
solution to this problem. This PR adds logic to create and return a
custom clap error when a parsed run command does not have the script
argument.

I added an appropriate test.

7bca4d3455 perf(ext/headers): cache iterableHeaders for immutable Headers (#20132)
This PR caches `_iterableHeaders` for immutable `Headers` increasing the
performance of `fetch` & server if headers are iterated.

Should close #19466 

I only cached immutable headers to address this comment
https://github.com/denoland/deno/issues/19466#issuecomment-1589892373
since I didn't find any occurrence of header mutation on immutable
headers. We can discuss caching for non-immutable, but I think this is a
great first step.

## BENCHMARK

### Server
```js
const addr = Deno.args[0] ?? "127.0.0.1:4500";
const [hostname, port] = addr.split(":");
const { serve } = Deno;

serve({ hostname, port: Number(port), reusePort: true }, (req) => {
  const headers = [...req.headers]; // req.headers are immutable, cannot set/append/delete
  return new Response("ok");
});

```
Used `wrk` with 5 headers
```
wrk -d 10s --latency -H "X-Deno: true" -H "Accept: application/json" -H "X-Foo: bar" -H "User-Agent: wrk" -H "Accept-Encoding: gzip, br" http://127.0.0.1:4500

3e5f890123 perf(ext/request): optimize Request constructor (#20141)
This PR optimizes `Request` constructor when `init` is not empty. This
path is also used by `fetch` when `options` argument is used
```js
fetch("https://deno.land", {
  method: "POST",
  body: 'land'
});
```

- Removed 3 extra calls to `headerListFromHeaders`
- Avoid `Object.keys` & `headerList` clone if `init.headers` is set
- Only empty `headersList` (`.splice`) if it's not already empty.

5e0b09a0a7 perf(ext/http): use ServeHandlerInfo class instead of object literal (#20122)
This PR improves performance of `Deno.Serve` when providing `info`
argument by creating `ServeHandlerInfo` class instead of creating an
object literal with a getter on every request.

```js
Deno.serve((_req, info) => new Response(info.remoteAddr.transport) });
```

----
### Drawbacks:

`.remoteAddr` is now not enumerable

```
ServeHandlerInfo {}
```
vs
```
{ remoteAddr: [Getter] }
```
It'll break any code trying to iterate through `info` keys (Doubt
there's anyone doing it though)

```js
Deno.serve((req, info) => {
  console.log(Object.keys(info).length === 0) // true;
  return new Response("yes");
});
