Game logging system

Eventually, we won't be able to log into the console, because normal game distribution will stop opening the console on Windows.

Also, WASM distributions will only support logging to the browser console; I'm not sure if it'll properly work by default or not.

So, we'll have to introduce a logging system (probably based on Microsoft's logger abstractions).

While we are at it, check if it's possible to pipe Raylib's logs to our logging system.

Look for `// TODO[#105]` to find places where logging would be required.
