Sorry for doing two things in a single PR, but it felt too small to split.

* The first commit I'm sure about: autowire PSR's `ClockInterface`, just like we do for e.g. the `EventDispatcherInterface`
* ~The second commit is something I want to propose after trying to write some docs on using Clock as a framework user: It isn't trivial to change the class of a definition from an application... and using a fixed moment in time while testing is *the* advantage of a clock component. So what about automatically switching to it when test mode is enabled?~ `@nicolas`-grekas
