Package Manager's services should use autowiring

Problem/Motivation

Drupal core 10.1 finally supports autowiring: https://www.drupal.org/node/3323122

This means that our service definitions can use autowiring by default. They will still have their string IDs so as not to break anything, but new services won't need to define their arguments manually, and we can change our existing services to autowire their own dependencies painlessly.
