Add Xenia Linux native to emulators list

[smurfxx]

Xenia emulator has now a native port to linux and even if in canary version it works very well. Will you add it to the available emulators? It should be interesting for all that portable devices like Steam Deck, Rog Ally and others.
The link to canary builds is this: https://github.com/xenia-canary/xenia-canary-releases
Thanks!
