Support ServiceClosureArgument in \Drupal\Component\DependencyInjection\Dumper\OptimizedPhpArrayDumper::dumpValue

Added a draft change record, we should add an example in the change record of how this looks in a services file. I don't understand this enough to add a good example.

Adapted the example from https://symfony.com/doc/current/service_container/service_closures.html for the CR.

#31 fails to apply, needs a reroll.

Rerolled patch on #31

Reuploading the patch after fixing issues.

No substantial changes since #34, hence RTBC.

I removed the service declaration from the change record, since that isn't working with the custom YamlFileLoader Drupal is currently using. But for service definitions built programmatically, this patch still brings some benefits.

(also added a change record)

Committed and pushed be795a8d99 to 11.x. Thanks!
