Updated PR for the printer design proposal

[rrahn]

This PR builds upon the original proposal of @marehr (#3227).

I changed from the print static member function to overloading the function call operator of the printer classes. Using this idea, we can now test wether a printer is invocable for a given output stream and the streamable argument. I also refactored some of the original default_printer code to simplify it. Among others, the is_printer is not needed anymore as we can use the invocable concept. For investigating errors I kept the concept printable_with which is basically just an alias for the invocable concept. In addition, I added documentation. Once this is done, we can look for more debug_stream instances that can be replaced with the printer mechanism.
