Emulators: Add support for suyu

[sounddrill31]

Code contributions (pull requests) are currently not being accepted while majority of code base is being rewritten for Playnite 11.

Please wait with any pull requests after P11 is at least in beta state.

This is just a teeny tiny emulator profile PR so ^ shouldn't matter, right?

I know the current decision is to not add Suyu based on https://github.com/JosefNemec/Playnite/issues/3824 and https://github.com/JosefNemec/Playnite/issues/3723 but it's here if you need it.
