Config: Handle unknown system strings better
Currently, a simple typo in the system name will trigger an assert message that complains about a "programming error". This is not user friendly and misleading. So this changes GetSystemFromName to return an std::optional, which allows for callers to check whether the system exists and handle failures better.
