Implemented a GitHub Actions testing pipeline (#575)

* Implemented a GitHub Actions testing pipeline
* Disabled potential failed annotations
* Added non parallel variant without prebuild
* Simplified expressions
* Combined tests, build binaries on ubuntu for faster completion
* String usage fix
* Triggering pipeline
