fix(ext/node): panic on 'worker_threads.receiveMessageOnPort' (#23386) 
Closes https://github.com/denoland/deno/issues/23362

Previously we were panicking if there was a pending read on a
port and `receiveMessageOnPort` was called. This is now fixed
by cancelling the pending read, trying to read a message and
resuming reading in a loop.

perf(cli): use new deno_core timers (#22569) 
Improves #19100 

Fixes #20356

Replaces #20428



Changes made in deno_core to support this:

 - [x] Errors must be handled in setTimeout callbacks
 - [x] Microtask ordering is not-quite-right
 - [x] Timer cancellation must be checked right before dispatch
 - [x] Timer sanitizer
 - [x] Move high-res timer to deno_core
 - [x] Timers need opcall tracing

chore(ext/web): refactor timer ops before landing op sanitizer (#22435) 
Splitting the sleep and interval ops allows us to detect an interval
timer. We also remove the use of the `op_async_void_deferred` call.

A future PR will be able to split the op sanitizer messages for timers
and intervals.

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:

```

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.

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

This commit refactors how we access "core", "internals" and

Instead of capturing them from "globalThis.__bootstrap" namespace, we

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

perf(ext/streams): optimize streams (#20649) 
This PR introduces several optimizations to streams

### Highlights:
- `ReadableStream` constructor: +20% iter/s.
- `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.

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.

refactor: rewrite ops that use 'deferred' to use 'op2(async(lazy))' (#20303) 
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".

chore: update to Rust 1.72 (#20258) 
<!--
Before submitting a PR, please read https://deno.com/manual/contributing

1. Give the PR a descriptive title.

  Examples of good title:
    - fix(std/http): Fix race condition in server
    - docs(console): Update docstrings
    - feat(doc): Handle nested reexports

  Examples of bad title:
    - fix #7123
    - update docs
    - fix bugs

2. Ensure there is a related issue and it is referenced in the PR text.
3. Ensure there are tests that cover the changes.
4. Ensure `cargo test` passes.
5. Ensure `./tools/format.js` passes without changing files.
6. Ensure `./tools/lint.js` passes.
7. Open as a draft PR if your work is still in progress. The CI won't
run
   all steps, but you can add '[ci]' to a commit message to force it to.
8. If you would like to run the benchmarks on the CI, add the 'ci-bench'
label.

perf(ext/event): replace ReflectHas with object lookup (#20190) 
This PR optimizes event dispatch by replacing `ReflectHas` with object
lookup. I also made `isSlottable` return `false` since AFAIK there
aren't any slottables nodes in Deno

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.
