Externals: Add libfmt 5.3.0 to externals
Allows us to migrate off of printf specifiers and have more type-safe formatting facilities. It also allows for custom type support as well. fmt is also on track to have part of it standardized within C++2a, so this will also lessen the transitional work necessary later on by allowing new code to use it. This simply adds the library but doesn't do anything with it yet.
