This patch fixes stdin read hanging on user input when switching tty
mode on Windows
Fixes #21111
On Windows, when switching from line to raw mode:
- Cancel ongoing console read by writing a return keypress to its input
buffer. This blocks the main thread until any ongoing read has been
cancelled to prevent interference with the screen state.
- On the read thread, restore the cursor position to where it was before
writing the enter, undoing its effect on the screen state.
- Restart reading and notify the main thread.
This is a primordialization effort to improve resistance against users
tampering with the global `Object` prototype.

1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.

This PR adds private `[REF]()` and `[UNREF]()` methods to Stdin class,
and call them from Node.js polyfill layer (`TTY` class). This enables
`process.stdin.unref()` and `process.stdin.ref()` for the case when
stdin is terminal.
closes #21796
Embedders may have special requirements around file opening, so we add a
new `check_open` permission check that is called as part of the file
open process.
Due to a terminating NUL that was placed in a `r#` string, we were not
actually NUL-terminating pipe names on Windows. While this has no
security implications due to the random nature of the prefix, it would
occasionally cause random failures when the trailing garbage would make
the pipe name invalid.

Investigating https://github.com/denoland/deno/issues/22574
Unable to reproduce with a unit test, but assuming that it's a name
collision or create pipe/open pipe race, and adding some additional
diagnostics.
Gets us closer to solving #20707.
Rewrites the `TestEventSender`:
- Allow for explicit creation of multiple streams. This will allow for
one-std{out,err}-per-worker
- All test events are received along with a worker ID, allowing for
eventual, proper parallel threading of test events.
In theory this should open up proper interleaving of test output,
however that is left for a future PR.
I had some plans for a better performing synchronization primitive, but
the inter-thread communication is tricky. This does, however, speed up
the processing of large numbers of tests 15-25% (possibly even more on
100,000+).
Before
```
ok | 1000 passed | 0 failed (32ms)
ok | 10000 passed | 0 failed (276ms)
```
After
```
ok | 1000 passed | 0 failed (25ms)
ok | 10000 passed | 0 failed (230ms)
```
Follow up to #22157.
This leaves us with 4 usages of `ensureFastOps()` in `deno` itself.
There's also about 150 usages of `Deno.core.ops.<op_name>` left as well.
For removal in Deno v2. There are two issues:
1. Any script being run causes the output of `warnOnDeprecatedApi()` to
be printed, even when none of the `rid` properties are called.
2. `.rid` of these classes is used in multiple tests. I'm not sure how
to account for that. I thought of having `STDIN_RID`, and friends,
constants, whose values can be shared between the tests and the classes
themselves. Should we go with that or do something else?

This change:
1. Implements `Deno.stdin.isTerminal()`, `Deno.stdout.isTerminal()` and
`Deno.stderr.isTerminal()`.
2. Deprecates `Deno.isatty()` for removal in Deno v2, in favour of the
above instance methods.
3. Replaces use of `Deno.isatty()` with the above instance methods.

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.
