This unflags --experimental-require-module so require(esm) can be
used without the flag. For now, when require() actually encounters
an ESM, it will still emit an experimental warning. To opt out
of the feature, --no-experimental-require-module can be used.
There are some tests specifically testing ERR_REQUIRE_ESM. Some
of them are repurposed to test --no-experimental-require-module.
Some of them are modified to just expect loading require(esm) to
work, when it's appropriate.

This patch implements a "module-sync" exports condition
for packages to supply a sycnrhonous ES module to the
Node.js module loader, no matter it's being required
or imported. This is similar to the "module" condition
that bundlers have been using to support `require(esm)`
in Node.js, and allows dual-package authors to opt into
ESM-first only newer versions of Node.js that supports
require(esm) while avoiding the dual-package hazard.
```json
{
"type": "module",
"exports": {
"node": {
// On new version of Node.js, both require() and import get
// the ESM version
"module-sync": "./index.js",
// On older version of Node.js, where "module" and
// require(esm) are not supported, use the transpiled CJS version
// to avoid dual-package hazard. Library authors can decide
// to drop support for older versions of Node.js when they think
// it's time.
"default": "./dist/index.cjs"
},
// On any other environment, use the ESM version.
"default": "./index.js"
}
}
```
We end up implementing a condition with a different name
instead of reusing "module", because existing code in the
ecosystem using the "module" condition sometimes also expect
the module resolution for these ESM files to work in CJS
style, which is supported by bundlers, but the native
Node.js loader has intentionally made ESM resolution
different from CJS resolution (e.g. forbidding `import
'./noext'` or `import './directory'`), so it would be
semver-major to implement a `"module"` condition
without implementing the forbidden ESM resolution rules.
For now, this just implments a new condition as semver-minor
so it can be backported to older LTS.

This patch adds `require()` support for synchronous ESM graphs under
the flag `--experimental-require-module`
This is based on the the following design aspect of ESM:
- The resolution can be synchronous (up to the host)
- The evaluation of a synchronous graph (without top-level await) is
also synchronous, and, by the time the module graph is instantiated
(before evaluation starts), this is is already known.
If `--experimental-require-module` is enabled, and the ECMAScript
module being loaded by `require()` meets the following requirements:
- Explicitly marked as an ES module with a `"type": "module"` field in
the closest package.json or a `.mjs` extension.
- Fully synchronous (contains no top-level `await`).
`require()` will load the requested module as an ES Module, and return
the module name space object. In this case it is similar to dynamic
`import()` but is run synchronously and returns the name space object
directly.
```mjs
// point.mjs
export function distance(a, b) {
return (b.x - a.x) ** 2 + (b.y - a.y) ** 2;
}
class Point {
constructor(x, y) { this.x = x; this.y = y; }
}
export default Point;
```
```cjs
const required = require('./point.mjs');
// [Module: null prototype] {
// default: [class Point],
// distance: [Function: distance]
// }
console.log(required);
(async () => {
const imported = await import('./point.mjs');
console.log(imported === required); // true
})();
```
If the module being `require()`'d contains top-level `await`, or the
module graph it `import`s contains top-level `await`,
[`ERR_REQUIRE_ASYNC_MODULE`][] will be thrown. In this case, users
should load the asynchronous module using `import()`.
If `--experimental-print-required-tla` is enabled, instead of throwing
`ERR_REQUIRE_ASYNC_MODULE` before evaluation, Node.js will evaluate the
module, try to locate the top-level awaits, and print their location to
help users fix them.

1. Adds a link to the WinterCG Runtime Keys proposal draft spec in the
documentation for the `export` condition.
2. Adds a criteria to add more export conditions to the Node.js docs:
they should be Node.js core-relevant.
3. Removes the "deno" and "react-native" export conditions from the core
docs with the expectation that readers will follow the link to the
Runtime Keys proposal draft spec to learn about them and more.

Corepack:
Node.js now includes Corepack, a script that acts as a bridge between
Node.js projects and the package managers they are intended to be used
with during development.
In practical terms, Corepack will let you use Yarn and pnpm without
having to install them - just like what currently happens with npm,
which is shipped in Node.js by default.

Main changes:
- Replace current HTML anchor generation to match
header anchor generation in Github markdown.
- Remove unnecessary double namespacing on generated anchors/links (E.G.
`esm.md#loaders` instead of `esm.md#esm_loaders`).
- Anchors/links are automatically prefixed with their respective modules
when concatenated for usage in `all.html`.
Benefits:
- All anchor links within and between markdown API docs actually work.
- Adding new anchor links no longer requires contributors to generate
the HTML docs first to look up the correct anchors.
- Anchors are much shorter.
- All previous anchor links are preserved by generating hidden legacy
anchors.
