Formatting fixes.
Add comment about SSE2 builds not working on non-AVX(2) CPUs.
Don't build tests.
Prepare artifacts:
Switch to PowerShell.
Rename xenia.exe to xenia-canary.exe.
Add Releases:
This allows GitHub Actions to have a link to the latest artifacts like AppVeyor, except not slow as fuck.
Currently AVX-only since users will get confused which one to download (this is also why vfs-dump isn't included in the zip), and I don't know how to use the upload_url from another job configuration.
Releases won't be created for PRs.
You can download the latest Release from here: https://github.com/xenia-canary/xenia-canary/releases/latest/download/xenia-canary.zip
