RFR: 8279437: [JVMCI] exception in HotSpotJVMCIRuntime.translate can exit the VM

[Doug Simon]

This PR addresses the problem reported in JDK-8279437 by adding support for transferring exceptions from HotSpot into libgraal (the other way around was already supported).
It also improves the translation of exceptions by:
* using a native (resource) buffer more directly for serializing an exception
* changing the serialization format to be a gzipped binary representation as it is much smaller than the string representation currently used and avoids having to worry about special characters (e.g. a `|` in an exception's message string).

It also adds the `jvmci.ForceTranslateFailure` option to allow testing handling of failures in `HotSpotJVMCIRuntime.translate`. See https://github.com/oracle/graal/commit/b3a6ce471e0d116196d6fde1c62377191f5db4ec for such a test.
