Generate RuSTy Binaries on push

Is your feature request related to a problem? Please describe.
We should try and publish binaries for windows and Linux ideally on every change on master, but if not possible then on every release.

Describe the solution you'd like
When a git push on master happens, the build artifacts will be available for download
See : https://github.com/actions/upload-artifact
The files we would provide are :

• Linux standard binary (x86_64-unknown-linux-gnu)
• Standalone linux binary (x86_64-unknown-linux-musl)
• Windows standalone binary for 64bit windows

When building a release, these artifacts should be automatically uploaded to the release assets.

Additional context
This feature would provide quick access to our latest binary to use while testing without having to install a full rust and llvm toolchain. The required LLVM toolchain is hard to install on windows
