Add github workflow and build on major operating systems

[imanushin]

Add build on GitHub. Actions should be enabled in local repository.

Current build is inefficient, because we compile and build one the same JVM (so, we compile three times more frequent than needed). Better solution is to run each test on multiple JVMs and multiple Gradle distributions, however that will be done in further PRs.

As per as some tests don't support Java 17 (because of compatibility with Gradle 7), only Java 8 is used for testing
