Regardless of the value of the `"type"` field, `.mjs` files are
always treated as ES modules and `.cjs` files are always treated
as CommonJS.

This ensures files with unknown extensions like foo.bar are not
loaded as CJS/ESM when imported as a main entry point and makes
sure that those files would maintain the same format even if loaded
after the main entrypoint.

`--es-module-specifier-resolution` is the only flagged portion of the
ESM implementation that does not have the word experimental in the flag
name. This commit changes the flag to:
`--experimental-specifier-resolution`
`--es-module-specifier-resolution` remains as an alias for backwards
compatibility but it is no longer documented.

The use of dashes -- in general, but especially in our docs -- can be
problematic. It is used inconsistently and there is always another form
of punctuation that is as good or better for the situation. In an effort
to reduce the number of variations we use to display the same types of
information, remove the various uses of dashes from the documentation.

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`).

Renames the `--loader` cli argument to `--experimental-loader`. This is
to clearly indicate the esm loader feature as experimental even after
esm is no longer experimental.
Also minorly alters the `--experimental-loader` docs to say that the
passed loader can be an esm module.

This reintroduces the dot main in exports as discussed in the previous
Node.js modules meeting.
The implementation includes both CommonJS and ES module resolution with
the associated documentation and resolver specification changes.
In addition to the dot main, "exports" as a string or direct fallback
array is supported as well.

we can move them out of the "experimental" status. They will still
be behind the `--experimental-modules` flag until the entire esm
