fix: strict type check for cross realms (#21669) 
Deno v1.39 introduces `vm.runInNewContext`. This may cause problems when
using `Object.prototype.isPrototypeOf` to check built-in types.

```js
import vm from "node:vm";

const err = new Error();
const crossErr = vm.runInNewContext(`new Error()`);

console.assert( !(crossErr instanceof Error) );
console.assert( Object.getPrototypeOf(err) !== Object.getPrototypeOf(crossErr) );
```

This PR changes to check using internal slots solves them.

current: 

```
> import vm from "node:vm";
undefined
> vm.runInNewContext(`new Error("message")`)
Error {}
> vm.runInNewContext(`new Date("2018-12-10T02:26:59.002Z")`)
Date {}
```

this PR:

```
> import vm from "node:vm";
undefined
> vm.runInNewContext(`new Error("message")`)
Error: message

perf: remove opAsync (#21690) 
`opAsync` requires a lookup by name on each async call. This is a
mechanical translation of all opAsync calls to ensureFastOps.

The `opAsync` API on Deno.core will be removed at a later time.

chore: ensure that each op provided to ensureFastOps is only used once (#21689) 
When we migrate to op-import-per-extension, we will want to ensure that
ops have one and only one place where they are imported. This tackles
the ops that are imported via `ensureFastOps`, but does not yet tackle
direct `ops` imports.

Landing ahead of https://github.com/denoland/deno_core/pull/393

1.39.0 (#21560) 
Bumped versions for 1.39.0

Please ensure:
- [x] Target branch is correct (`vX.XX` if a patch release, `main` if
minor)
- [x] Crate versions are bumped correctly
- [x] deno_std version is incremented in the code (see
`cli/deno_std.rs`)
- [x] Releases.md is updated correctly (think relevancy and remove
reverts)

To make edits to this PR:
```shell
git fetch upstream release_1_39.0 && git checkout -b release_1_39.0 upstream/release_1_39.0
```

refactor: pull 'core', 'internals', 'primordials' from ES module (#21462) 
This commit refactors how we access "core", "internals" and
"primordials" objects coming from `deno_core`, in our internal JavaScript code.

Instead of capturing them from "globalThis.__bootstrap" namespace, we
import them from recently added "ext:core/mod.js" file.

chore: bump deno_core and update tests (#21467) 
Landing changes required for
https://github.com/denoland/deno_core/pull/359

We needed to update 99_main.js and a whole load of tests.

API changes:

- setPromiseRejectCallback becomes setUnhandledPromiseRejectionHandler.
The function is now called from eventLoopTick.
- The promiseRejectMacrotaskCallback no longer exists, as this is
automatically handled in eventLoopTick.
- ops.op_dispatch_exception now takes a second parameter: in_promise.
The preferred way to call this op is now reportUnhandledException or
reportUnhandledPromiseRejection.

feat(ext/web): add ImageData Web API (#21183) 
Fixes #19288

Adds the `ImageData` Web API. 

This would be beneficial to projects using `ImageData` as a convenient
transport layer for pixel data. This is common in Web Assembly projects
that manipulate images. Having this global available in Deno would
improve compatibility of existing JS libraries.

refactor: use resourceForReadableStream for fetch (#20217) 
Switch `ext/fetch` over to `resourceForReadableStream` to simplify and
unify implementation with `ext/serve`. This allows us to work in Rust
with resources only.

Two additional changes made to `resourceForReadableStream` were
required:

- Add an optional length to `resourceForReadableStream` which translates
to `size_hint`
 - Fix a bug where writing to a closed stream that was full would panic

fix(ext/web): Aggregate small packets for Resource implementation of 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.

perf(ext/node): Optimise Buffer string operations (#20158) 
Extracted from https://github.com/denoland/deno/pull/17815

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.

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();
    }
  })
```

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.

fix(ext/file): resolve unresolved Promise in Blob.stream (#20039) 
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:6ba245fe25/ext/web/06_streams.js (L2026)
which ends up calling `readIntoRequest.closeSteps(chunk);` in
6ba245fe25/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
```

fix: call setIsTrusted for generated events (MessageEvent) (#19919) 
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.

fix(dts): make globals available on globalThis (#19438) 
This PR changes Web IDL interfaces to be declared with `var` instead of
`class`, so that accessing them via `globalThis` does not raise type

Reland "refactor(core): cleanup feature flags for js source inclusion" (#19519) 
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()`.

refactor(serde_v8): split ZeroCopyBuf into JsBuffer and ToJsBuffer (#19566) 
`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.

perf: don't run microtask checkpoint if macrotask callback did no work (#19492)

rejections, so it's wasteful to run microtask checkpoint 
additionally twice on each tick of the event loop.

Revert "refactor(core): cleanup feature flags for js source inclusion… (#19490) 
… (#19463)"

This reverts commit ceb03cfb03.

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.

refactor(core): cleanup feature flags for js source inclusion (#19463) 
Remove `ExtensionFileSourceCode::LoadedFromFsDuringSnapshot` and feature
`include_js_for_snapshotting` since they leak paths that are only
applicable in this repo to embedders. Replace with feature
`exclude_js_sources`. Additionally the feature
`force_include_js_sources` allows negating it, if both features are set.
We need both of these because features are additive and there must be a
way of force including sources for snapshot creation while still having
the `exclude_js_sources` feature. `force_include_js_sources` is only set
for build deps, so sources are still excluded from the final binary.

You can also specify `force_include_js_sources` on any extension to
override the above features for that extension. Towards #19398.

But there was still the snapshot-from-snapshot situation where code
could be executed twice, I addressed that by making `mod_evaluate()` and
scripts like `core/01_core.js` behave idempotently. This allowed
unifying `ext::init_ops()` and `ext::init_ops_and_esm()` into
`ext::init()`.

fix(ext/web): Copy EventTarget list before dispatch (#19360) 
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.
