Anna Henningsen ed24c19002 worker: refactor worker.terminate()
At the collaborator summit in Berlin, the behaviour of
`worker.terminate()` was discussed.

In particular, switching from a callback-based to a Promise-based API
was suggested. While investigating that possibility later, it was
discovered that `.terminate()` was unintentionally synchronous up
until now (including calling its callback synchronously).

Also, the topic of its stability has been brought up. I have performed
two manual reviews of the native codebase for compatibility with
`.terminate()`, and performed some manual fuzz testing with the test
suite. At this point, bugs with `.terminate()` should, in my opinion,
be treated like bugs in other Node.js features.
(It is possible to make Node.js crash with `.terminate()` by messing
with internals and/or built-in prototype objects, but that is already
the case without `.terminate()` as well.)

This commit:

- Makes `.terminate()` an asynchronous operation.
- Makes `.terminate()` return a `Promise`.
- Runtime-deprecates passing a callback.
- Removes a warning about its stability from the documentation.
- Eliminates an unnecessary extra function from the C++ code.

A possible alternative to returning a `Promise` would be to keep the
method synchronous and just drop the callback. Generally, providing
an asynchronous API does provide us with a bit more flexibility.

Node.js Core Tests

This directory contains code and data used to test the Node.js implementation.

For a detailed guide on how to write tests in this directory, see the guide on writing tests.

On how to run tests in this directory, see the contributing guide.

For the tests to run on Windows, be sure to clone Node.js source code with the autocrlf git config flag set to true.

Test Directories

Directory Runs on CI Purpose
abort Yes Tests for when the --abort-on-uncaught-exception flag is used.
addons Yes Tests for addon functionality along with some tests that require an addon.
async-hooks Yes Tests for async_hooks functionality.
benchmark No Test minimal functionality of benchmarks.
cctest Yes C++ tests that are run as part of the build process.
code-cache No Tests for a Node.js binary compiled with V8 code cache.
common Common modules shared among many tests. Documentation
doctool Yes Tests for the documentation generator.
es-module Yes Test ESM module loading.
fixtures Test fixtures used in various tests throughout the test suite.
internet No Tests that make real outbound network connections. Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections.
js-native-api Yes Tests for Node.js-agnostic n-api functionality.
known_issues Yes Tests reproducing known issues within the system. All tests inside of this directory are expected to fail. If a test doesn't fail on certain platforms, those should be skipped via known_issues.status.
message Yes Tests for messages that are output for various conditions (console.log, error messages etc.)
node-api Yes Tests for Node.js-specific n-api functionality.
parallel Yes Various tests that are able to be run in parallel.
pseudo-tty Yes Tests that require stdin/stdout/stderr to be a TTY.
pummel No Various tests for various modules / system functionality operating under load.
sequential Yes Various tests that must not run in parallel.
testpy Test configuration utility used by various test suites.
tick-processor No Tests for the V8 tick processor integration. The tests are for the logic in lib/internal/v8_prof_processor.js and lib/internal/v8_prof_polyfill.js. The tests confirm that the profile processor packages the correct set of scripts from V8 and introduces the correct platform specific logic.
v8-updates No Tests for V8 performance integration.
