I noticed
[`set_response_body`](ce42f82b5a/ext/http/service.rs (L439-L443))
was unexpectedly hot in profiles, with most of the time being spent in
`memmove`.
It turns out that `ResponseBytesInner` was _massive_ (5624 bytes), so
every time we moved a `ResponseBytesInner` (for instance in
`set_response_body`) we were doing a >5kb memmove, which adds up pretty
quickly.
This PR boxes the two larger variants (the compression streams),
shrinking `ResponseBytesInner` to a reasonable 48 bytes.

Benchmarked with a simple hello world server:
```ts
// hello-server.ts
Deno.serve((_req) => {
return new Response("Hello world");
});
// run with `deno run -A hello-server.ts`
// in separate terminal `wrk -d 10s http://127.0.0.1:8000`
```
Main:

So a nice ~15% bump. (With response body compression, the gain is ~10%
for gzip and neutral for brotli)
- upgrade to v8 12.8
- optimizes DataView bigint methods
- fixes global interceptors
- includes CPED methods for ALS
- fix global resolution
- makes global resolution consistent using host_defined_options.
originally a separate patch but due to the global interceptor bug it
needs to be included in this pr for all tests to pass.

This PR resolves a handful of issues with child_process IPC. In
particular:
- We didn't support sending typed array views over IPC
- Opening an IPC channel resulted in the event loop never exiting
- Sending a `null` over IPC would terminate the channel
- There was some UB in the read implementation (transmuting an `&[u8]`
to `&mut [u8]`)
- The `send` method wasn't returning anything, so there was no way to
signal backpressure (this also resulted in the benchmark
`child_process_ipc.mjs` being misleading, as it tried to respect
backpressure. That gave node much worse results at larger message sizes,
and gave us much worse results at smaller message sizes).
- We weren't setting up the `channel` property on the `process` global
(or on the `ChildProcess` object), and also didn't have a way to
ref/unref the channel
- Calling `kill` multiple times (or disconnecting the channel, then
calling kill) would throw an error
- Node couldn't spawn a deno subprocess and communicate with it over IPC
This commit duplicates ops from "ext/fetch" to "ext/node" to
kick off a bigger rewrite of "node:http".
Most of duplication is temporary and will be removed as these
ops evolve.
Support `MessagePort.once` in Node mode and enable relevant
`worker_threads` test. Noticed that another Node test was passing as
well, so I enabled that too.
This change aims to replace all relative import specifiers targeted at
`tests/util/std` with mapped ones (using a `deno.json` file). Towards
updating the `std` git submodule.
Sending ALPN to a proxy, and then when tunneling, requires better
juggling of TLS configs. This improves the choice of TLS config in the
proxy connector, based on what reqwest does. It also includes some
`ext/fetch/tests.rs` that check the different combinations.
Fixes #24632
Fixes #24691
