WASI p1 support

[usiegl00]

With SubstrateVM now compiling to WASI p1 with --tool:svm-wasm, next is TruffleRuby running on WASM.
I tried running the following with --tool:svm-wasm, but it looks like the --language:ruby flag was removed from the native-image tool.

Line 86 in d583795

native-image -o native-ruby --language:ruby

Any insight into hacking the mx build to target wasm would be very helpful.

Right, that part is outdated, --language:ruby is a legacy macro and that's gone now.

These days, you would get the jars from Maven for org.graalvm.polyglot:ruby, and either use the Native Image Maven/Gradle plugin or get the full classpath of the dependencies via something like mvn dependency:build-classpath.
