More code cleanup

- Set character set to multi-byte (this is because the game is also build with it).
- Utility function 'FileExists' now takes a raw string pointer, this avoids having to construct a fs::path each time its getting called (which is quite a lot!).
- Performed overall cleanup to code containing logic to override load paths. Mostly removing unnecessary copy constructions.
