Xenia-AppImage

This is an attempt of packing xenia as appimage

Well it's working somehow, but I don't know how to use it, so test it and tell me what do you think?

I guess it's save to use, only tested in ubuntu 24.04

By now to run it, you may need to extract the appimage with the coammand `./ Xenia-canary-x86_64.AppImage --appimage-extract` and run by `./AppRun`, this happens due to so many cache folder created by xenia in his own directory, I'll try to find a solution for it soon
