Could we implement an instance of `PPCallbacks` that contains
`CppFilePreambleCallbacks` and forwards to that specific method instead?
The reason is that we're not really delegating other methods in this calls(nor
should we, the implementation would be too compilcated).
Having a class that contains `CppFilePreambleCallbacks &Collector` and calling
`Collector.InclusionDirective` seems perfectly fine, though: its purpose is
clear and the implementation is easy.
