RFR: 8248321: [JVMCI] improve libgraal logging and fatal error handling

[Doug Simon]

Please review this change that:

1. Sends log output from libgraal for options such as -Dlibgraal.PrintGC=true to HotSpot's tty stream.
2. Forwards a fatal error in libgraal to HotSpot's report_fatal function so that a proper hs_err_pid crash log is produced.
3. Adds coarse grained JVMCI events to the hs_eer_pid crash log that can help diagnose libgraal crashes.

Testing: hs-tier1,hs-tier2,hs-tier3-graal,hs-tier4-graal

I’ve also tested this on a JDK 16 libgraal build (thanks to Bob’s recent fixes <https://github.com/oracle/graal/pull/2635>) using the -Dlibgraal.CrashAtIsFatal=true option introduced for testing purposes. Here are extracts from the resulting hs_err_pid log:
