This feature provides timings for the supports and resolve methods for each individual argument value resolver. It was already possible to see the `controller.get_arguments` timing, but it was impossible to track a possible performance issue any further without using different tools. I've explicitly added the `supports` method as well, as it might otherwise hide performance issues. The `ServiceValueResolver` for example, does a `container::has`, which in turn might trigger a factory method, which might trigger a query for example.
~~Due to the feature freeze I've already added this to 4.2. If for some reason it's okay to still merge it into 4.1, I can update the upgrade files.~~ - Changed to 4.1
