RFR: 8283612: IGV: Remove Graal module

Fri Jun 10 06:09:33 UTC 2022

This pull request removes Graal module in Ideal Graph Visualizer. I think you might know that Graal JIT compiler was removed from OpenJDK in version 17. So IGV doesn't need to support Graal's dump files any more. It is noted that GraalVM has its own version of IGV (https://www.graalvm.org/22.1/tools/igv/).

It seems that there are no test cases related to Graal module. I've built IGV, run it and opened the graphs. Those were all successful.
