fatal: Implement Service (#3573)

Browse source 
* fatal: Implement Service

This PR adds a basic implementation of fatal service, guest processes call it when there is something wrong. But since we can already have all informations by debugging it's not really useful.
In any case, that's avoid an unimplemented service exception. Structs/Enum are based on Atmosphère source code.

After logs the error report, I call SvcBreak. Feedbacks are welcome on this, since some guests calls it right after fatal service so I can remove it if needed.

* Addresses gdkchan feedback
