Implements `WebSocket` over http/2. This requires a conformant http/2
server supporting the extended connect protocol.
Passes approximately 100 new WPT tests (mostly `?wpt_flags=h2` versions
of existing websockets APIs).
This is implemented as a fallback when http/1.1 fails, so a server that
supports both h1 and h2 WebSockets will still end up on the http/1.1
upgrade path.
The patch also cleas up the websockets handshake to split it up into
http, https+http1 and https+http2, making it a little less intertwined.
This uncovered a likely bug in the WPT test server:

This PR adds unstable `Deno.cron` API to trigger execution of cron jobs.
* State: All cron state is in memory. Cron jobs are scheduled according
to the cron schedule expression and the current time. No state is
persisted to disk.
* Time zone: Cron expressions specify time in UTC.
* Overlapping executions: not permitted. If the next scheduled execution
time occurs while the same cron job is still executing, the scheduled
execution is skipped.
* Retries: failed jobs are automatically retried until they succeed or
until retry threshold is reached. Retry policy can be optionally
specified using `options.backoffSchedule`.
This PR adds a new unstable "bring your own node_modules" (BYONM)
functionality currently behind a `--unstable-byonm` flag (`"unstable":
["byonm"]` in a deno.json).
This enables users to run a separate install command (ex. `npm install`,
`pnpm install`) then run `deno run main.ts` and Deno will respect the
layout of the node_modules directory as setup by the separate install
command. It also works with npm/yarn/pnpm workspaces.
For this PR, the behaviour is opted into by specifying
`--unstable-byonm`/`"unstable": ["byonm"]`, but in the future we may
make this the default behaviour as outlined in
https://github.com/denoland/deno/issues/18967#issuecomment-1761248941
This is an extremely rough initial implementation. Errors are
terrible in this and the LSP requires frequent restarts. Improvements
will be done in follow up PRs.
Right now, if one of the linters fails, the all other ones continue
running in the background. This fixes this by waiting until all linters
are done before settling.
Running `tools/wpt.ts` with a filter would cause an error if there were
extra, leftover expectations in expectations.json. These errors would
not appear if no filter was passed, often leaving the filtered version
of the test runner broken.
This also introduces a smarter bit of logic where filters can be
specified with a leading slash (`tools/wpt.ts run -- /url` is equivalent
to `tools/wpt.ts run -- url`)
Makes the prebuilt installation a bit more reliable:
- Check for 200
- Check for an executable header (MZ, ELF, etc)
- Download to a .temp file until we're certain the file is valid
- If multiple requests for a tool are made, only run one task
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 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
```
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.
Fixes the WPT tests that test w/invalid codes. Also explicitly ignoring
some h2 tests to hopefully prevent flakes.
The previous changes to WebSocketStream introduced a bug where the close
errors were not made available if the `pull` method was re-entrant.
