Our CI already run test files in parallel, having `node:test` spawns
child processes concurrently could lead to oversubscribing the CI
machine. This commit sets the `concurrency` depending
on the presence of `TEST_PARALLEL` in the env, so running the test
file individually still spawns child processes concurrently, and
running the whole test suite does not oversubscribe the machine.

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.

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.
