Studying these recent changes led me back to #14851 which added jtreg propeties:

- `jdk.hasLibgraal`: the libgraal shared library file is present
- `vm.libgraal.enabled`: libgraal is used as JIT compiler

The latter now feels misleading, since libgraal can be "enabled" for use by non-CompilerBroker compilations, without being used as the JIT compiler.  (I'm here b/c we're assembling a distro doing exactly that.)

Would it make sense to rename the latter, to reduce ambiguity in the tests?
