Léo Lam 05c8d229af 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.
