When circular loops involve references in properties, method calls or configurators, it is possible to properly instantiate the related services.
The current logic is broken: `ContainerBuilder` considers some of these loops as self-referencing circular references, leading to a runtime exception, and in similar situations, `PhpDumper` generates code that turns to infinite loops at runtime 💥. These badly handled situations happen with inlined definitions.
This PR fixes both classes by making them track which references are really part of the constructors' chain, including inline definitions.
It also fixes dumping infinite loops when dumping circular loops involving lazy services while proxy-manager-bridge is not installed.
