This replaces the internally used hard coded Node.js core module
list with the actual internal existent modules. That way all modules
are automatically picked up instead of having to update the list
manually.
This currently only applies to the REPL and to the Node.js `eval`
functionality (User passed `-e` or `--eval` arguments to Node without
`-i` or `--interactive`).

Warn when a non-existent property of an unfinished module.exports

of a hard-to-detect and hard-to-debug problem.
This mechanism is only used if `module.exports` is still a
regular object at the point at which the second, circular `require()`
happens.
The downside is that, temporarily, `module.exports` will have a
prototype other than `Object.prototype`, and that there may
be valid uses of accessing non-existent properties of unfinished
`module.exports` objects.

Adds the ability to `import` or `require` a package from within its
own source code. This allows tests and examples to be written using
the package name, making them easier to reuse by consumers of the
package.
Assuming the `name` field in `package.json` is set to `my-pkg`, its
test could use `require('my-pkg')` or `import 'my-pkg'` even if
there's no `node_modules/my-pkg` while testing the package itself.
An important difference between this and relative specifiers like
`require('../')` is that self-references use the public interface
of the package as defined in the `exports` field while relative
specifiers don't.
This behavior is guarded by a new experimental flag
(`--experimental-resolve-self`).

It has the nice feature that this cache does not only work in the same
file but it works for the whole current directory. So if the same file
is loaded in any other file from the same directory, it will also hit
this cache instead of having to resolve the file again.
To keep it backwards compatible with the old modules cache, it detects
invalidation of that cache.

This PR updates the current `--experimental-modules` implementation
based on the work of the modules team and reflects Phase 2 of our
new modules plan.
The largest differences from the current implementation include
* `packge.type` which can be either `module` or `commonjs`
- `type: "commonjs"`:
- `.js` is parsed as commonjs
- default for entry point without an extension is commonjs
- `type: "module"`:
- `.js` is parsed as esm
- does not support loading JSON or Native Module by default
- default for entry point without an extension is esm
* `--entry-type=[mode]`
- allows you set the type on entry point.
* A new file extension `.cjs`.
- this is specifically to support importing commonjs in the
`module` mode.
- this is only in the esm loader, the commonjs loader remains
untouched, but the extension will work in the old loader if you use
the full file path.
* `--es-module-specifier-resolution=[type]`
- options are `explicit` (default) and `node`
- by default our loader will not allow for optional extensions in
the import, the path for a module must include the extension if
there is one
- by default our loader will not allow for importing directories that
have an index file
- developers can use `--es-module-specifier-resolution=node` to
enable the commonjs specifier resolution algorithm
- This is not a “feature” but rather an implementation for
experimentation. It is expected to change before the flag is
removed
* `--experimental-json-loader`
- the only way to import json when `"type": "module"`
- when enable all `import 'thing.json'` will go through the
experimental loader independent of mode
- based on https://github.com/whatwg/html/issues/4315
* You can use `package.main` to set an entry point for a module
- the file extensions used in main will be resolved based on the
`type` of the module

We currently ignore invalid `main` entries in package.json files.
This does not seem to be very user friendly as it's certainly an
error if the `main` entry is not a valid file name. So instead of
trying to resolve the file otherwise, throw an error immediately to
improve the user experience.
To keep it backwards compatible `index.js` files in the same directory
as the `package.json` will continue to be resolved instead but that
behavior is now deprecated.

This patch removes `NativeModule.require` and
`NativeModule.requireWithFallbackInDeps`. The public loaders now
have to use a special method
`NativeModule.prototype.compileForPublicLoader()` to compile native
modules. In addition this patch moves the decisions of proxifying
exports and throwing unknown builtin errors entirely to public
loaders, and skip those during internal use - therefore `loaders.js`,
which is compiled during bootstrap, no longer needs to be aware of
the value of `--experimental-modules`.

The current caching logic broke by [0] because it used destructuring
on the module arguments. Since the exported property is a primitive
counting it up or down would not have any effect anymore in the module
that required that property.
The original implementation would cache all stat calls caused during
bootstrap. Afterwards it would clear the cache and lazy require calls
during runtime would create a new cascading cache for the then
loaded modules and clear the cache again.
This behavior is now restored. This is difficult to test without
exposing a lot of information and therfore the existing tests have
been removed (as they could not detect the issue).
With the broken implementation it caused each module compilation to
reset the cache and therefore minimizing the effect drastically.

- Remove `NativeModule._source` - the compilation is now entirely
done in C++ and `process.binding('natives')` is implemented
directly in the binding loader so there is no need to store
additional source code strings.
- Instead of using an object as `NativeModule._cached` and insert
into it after compilation of each native module, simply prebuild
a JS map filled with all the native modules and infer the
state of compilation through `mod.loading`/`mod.loaded`.
- Rename `NativeModule.nonInternalExists` to
`NativeModule.canBeRequiredByUsers` and precompute that
property for all the native modules during bootstrap instead
of branching in every require call during runtime. This also fixes
the bug where `worker_threads` can be made available with
`--expose-internals`.

Having an experimental feature behind a flag makes change
if we are expecting significant breaking changes to its API.
Since the Worker API has been essentially stable since

possibly not keeping the feature around has been voiced,
removing the flag and thereby reducing the barrier to experimentation,
and consequently receiving feedback on the implementation,
seems like a good idea.
