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.
