Define github actions workflows and publish binaries artifacts

Among the definition of github actions I've cleanup
* the build of examples as the project does not publish any example
* the usage of env variables in makefile
* the usage of `-Zunstable-options` in windows build (as no longer needed)

.cargo/config

 [target.x86_64-pc-windows-msvc]
-rustflags = ["-Ctarget-feature=+crt-static", "-Zunstable-options"]
+rustflags = ["-Ctarget-feature=+crt-static"]
