This PR adds closure service factories for the `DependencyInjection` component. There are 2 kinds of closures:
```php
use Symfony\Component\DependencyInjection\ContainerInterface;

// Closure with services/parameters as arguments
$container
    ->register('bar1', 'Bar')
    ->setFactory(function (Foo $foo, $bar) {
        return new Bar($foo->getQux(), $bar);
    })
    ->addArgument(new Reference('foo'))
    ->addArgument('%bar%')
;

// Pimple-like closure with container as an argument
$container
    ->register('bar2', 'Bar')
    ->setFactory(function (ContainerInterface $container) {
        return new Bar($container->get('foo')->getQux(), $container->getParameter('bar'));
    })
;
```
It would be useful for something like `ArrayFileLoader` described in #11953.
It's not callable, e.g. you can't pass `[$object, 'foo']`.
