Adding the per-realm binding data tracking introduced a call to a realm method when realm was potentially null. This is triggered whenever the function is called from `ContextifyContext::New` which passes `nullptr` as the `realm`.

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.
