As outlined in #25159, our beloved container suffers from a perf hit just because it has a second argument, and this second argument's default value makes it slower.
Let's fix this by inlining the value. This will put Symfony at a better rank on eg:
https://github.com/kocsismate/php-di-container-benchmarks
I benched also with the following script. The result is surprising (but matches the finding in #25159):
without the patch, it takes 2s, and with the patch, it's down to 1s (opcache enabled).
```php
require './vendor/autoload.php';
use Symfony\Component\DependencyInjection\Container;
$c = new Container();
$c->set('foo', new \stdClass());
$i = 10000000;
$s = microtime(1);
while (--$i) {
$c->get('foo');
}
echo microtime(true) - $s, "\n";
```
