Integration tests for fury:

• jdk_compatibility_tests: test fury compatibility across multiple jdk versions.
• latest_jdk_tests: test latest jdk.
• graalvm_tests: test graalvm native image support.
• jpms_tests: test JPMS module names.

Note that this integration_tests is not designed as a maven multi-module project on purpose, so we can introduce features of higher jdk version without breaking compilation for lower jdk, and add integration tests for other languages.
