This avoids initializing arrays that we never use, and simplifies the
implementation overall.

Major functional changes:

- Allow `import()` to work within loaders that require other loaders,
- Unflag the use of `Module.register`.

A new interface `Customizations` has been created in order to unify
`ModuleLoader` (previously `DefaultModuleLoader`), `Hooks` and
`CustomizedModuleLoader` all of which now implement it:

```ts
interface LoadResult {
  format: ModuleFormat;
  source: ModuleSource;
}

interface ResolveResult {
  format: string;
  url: URL['href'];
}

interface Customizations {
  allowImportMetaResolve: boolean;
  load(url: string, context: object): Promise<LoadResult>
  resolve(
    originalSpecifier:
    string, parentURL: string,
    importAssertions: Record<string, string>
  ): Promise<ResolveResult>
  resolveSync(
    originalSpecifier:
    string, parentURL: string,
    importAssertions: Record<string, string>
  ) ResolveResult;
  register(specifier: string, parentUrl: string): any;
  forceLoadHooks(): void;
  importMetaInitialize(meta, context, loader): void;
}
```

The `ModuleLoader` class now has `setCustomizations` which takes an
object of this shape and delegates its responsibilities to this object
if present.

Note that two properties `allowImportMetaResolve` and `resolveSync`
exist now as a mechanism for `import.meta.resolve` – since `Hooks`
does not implement `resolveSync` other loaders cannot use
`import.meta.resolve`; `allowImportMetaResolve` is a way of checking
for that case instead of invoking `resolveSync` and erroring.

Fixes #48515
Closes #48439

Some tests are assuming they will be run from a directory that do not
contain any quote or special character in its path. That assumption is
not necessary, using `JSON.stringify` or `pathToFileURL` ensures the
test can be run whatever the path looks like.

Follows @giltayar's proposed API:

> `register` can pass any data it wants to the loader, which will be
passed to the exported `initialize` function of the loader.
Additionally, if the user of `register` wants to communicate with the
loader, it can just create a `MessageChannel` and pass the port to the
loader as data.

The `register` API is now:

```ts
interface Options {
  parentUrl?: string;
  data?: any;
  transferList?: any[];
}

function register(loader: string, parentUrl?: string): any;
function register(loader: string, options?: Options): any;
```

This API is backwards compatible with the old one (new arguments are
optional and at the end) and allows for passing data into the new
`initialize` hook. If this hook returns data it is passed back to
`register`:

```ts
function initialize(data: any): Promise<any>;
```

**NOTE**: Currently there is no mechanism for a loader to exchange
ownership of something back to the caller.

- Always check stderr before stdout as the former would contain error
  information.
- Always match the full stdout to avoid surprises.
- Use `deepStrictEqual` when appropriate to get more informative test
  failures.
- Remove leading slashes from relative paths/URLs to not confuse them
  with absolute paths.
- Remove unnecessary `--no-warnings` flag.
