resourceForReadableStream (#20622)
We can go one level down in abstraction and avoid using the public
`ReadableStream` APIs.
This patch ~5% perf boost on small ReadableStream:

ReadableStream (#20570)
Fixes: #20569 by introducing a custom replacement for the tokio mpsc
channel that is byte-size backpressure-aware.
Using the testcase in the linked bug, we see all the small writes
aggregated into a single packet and HTTP frame.

Optimise Buffer's string operations, most significantly when dealing
with ASCII and UTF-16. Base64 and HEX encodings are affected to much
lesser degrees.
## Performance
### String length 15
With very small strings we're at break-even or sometimes even lose a tad
bit of performance from creating a `DataView` that ends up not paying
for itself.

performance is enormous.

This reverts commit
https://github.com/denoland/deno/commit/83426be6eead06c680ae527468aeaf8723543ff2.
Includes a regression test.

Rewrites 3 ops that used "op(deferred)" to use "op2(async(lazy))"
instead.
This will allow us to remove codepath for handling "deferred" ops in
"deno_core".

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();
}
})
```

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.

Fixes https://github.com/denoland/deno/issues/19866
|

This PR ensures that the original signal event is fired before any
dependent signal events.
---
The enabled tests fail on `main`:
```
assert_array_equals: Abort events fired in correct order expected property 0 to be
"original-aborted" but got "clone-aborted" (expected array ["original-aborted", "clone-aborted"]
got ["clone-aborted", "original-aborted"])
```

This PR fixes some crashing WPT tests due to an unresolved promise.

This could be a [stream spec](https://streams.spec.whatwg.org) bug
When `controller.close` is called on a byob stream, there's no cleanup
of pending `readIntoRequests`. The only cleanup of pending
`readIntoRequests` happen when `.byobRequest.respond(0)` is called, it
happens
here:https://github.com/denoland/deno/blob/6ba245fe2570b29e35a4fd296a196a58870b1e3c/ext/web/06_streams.js#L2026
which ends up calling `readIntoRequest.closeSteps(chunk);` in
https://github.com/denoland/deno/blob/6ba245fe2570b29e35a4fd296a196a58870b1e3c/ext/web/06_streams.js#L2070
To reproduce:
```js
async function byobRead() {
const input = [new Uint8Array([8, 241, 48, 123, 151])];
const stream = new ReadableStream({
type: "bytes",
async pull(controller) {
if(input.length === 0) {
controller.close();
// controller.byobRequest.respond(0); // uncomment for fix
return
}
controller.enqueue(input.shift())
},
});
const reader = stream.getReader({ mode: 'byob' });
const r1 = await reader.read(new Uint8Array(64));
console.log(r1);
const r2 = await reader.read(new Uint8Array(64));
console.log(r2);
}
await byobRead();
```
Running the script triggers:
```
error: Top-level await promise never resolved
```

This addresses issue #19918.
## Issue description
Event messages have the wrong isTrusted value when they are not
triggered by user interaction, which differs from the browser. In
particular, all MessageEvents created by Deno have isTrusted set to
false, even though it should be true.
This is my first ever contribution to Deno, so I might be missing
something.

`class`, so that accessing them via `globalThis` does not raise type
errors.

Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.

`ZeroCopyBuf` was convenient to use, but sometimes it did hide details
that some copies were necessary in certain cases. Also it made it way to easy
for the caller to pass around and convert into different values. This commit
splits `ZeroCopyBuf` into `JsBuffer` (an array buffer coming from V8) and
`ToJsBuffer` (a Rust buffer that will be converted into a V8 array buffer).
As a result some magical conversions were removed (they were never used)
limiting the API surface and preparing for changes in #19534.

Most of the time there's no firing timers, nor pending promise
rejections, so it's wasteful to run microtask checkpoint
additionally twice on each tick of the event loop.

(#19490)
… (#19463)"
This reverts commit ceb03cfb037cf7024a5048b17b508ddda59cfa05.
This is being reverted because it causes 3.5Mb increase in the binary
size,
due to runtime JS code being included in the binary, even though it's
already snapshotted.
