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

- `WritableStream` constructor: +50% iter/s.
- `TransformStream` constructor: +30% iter/s.
- `ReadableStream` iterator (both 2 and 20 chunks): +42% and +25%
iter/s.
- `ReadableByteStream` iterator (both 2 and 20 chunks): +39% and +20%
iter/s.

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.
