[Feature]: Auto discovered custom `if` statements Blade

### Feature Description

Is there a way to link custom `if` statements Blade to where its declared?  Like
```blade
@disk('s3')
    <div>.../<div>
@endisk
```
linked to
```php
class BladeServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        Blade::if('disk', fn (string $value) => config('filesystems.default') === $value);
    }
}
