add scripting integration for graalvm

[subes]

https://www.graalvm.org/latest/reference-manual/embed-languages/#compatibility-with-jsr-223-scriptengine

Since 23.1.0 this should work also easily on OpenJDK without running directly inside GraalVM

[n] Espresso for Java => won't do because espresso does not support eval: (*Espresso does not support evaluation (.eval) of Java sources.
[y] GraalJS already integrated as invesdwin-context-javascript
[y] GraalPy
[y] TruffleRuby
[n] FastR though abandoned (similar to renjin) => Won't do since not packaged anymore
[n] LLVM for C/C++-/Rust => Won't do because eval can only load code to then execute functions in it: https://www.graalvm.org/latest/reference-manual/llvm/Interoperability/ though the llvm bitcode generation from arbitrary source code could be automated, but is rather something to do at build-time instead at runtime. Will be investigated as part of invesdwin/invesdwin-scripting#13
