Florian HotzeandGitHub 42b8505bef [jsscripting] Fix memory leak that crashes openHAB (#13824)
* [jsscripting] Fix memory-leak caused by com.oracle.truffle.host.HostObject

Fixes this memory leak by making the HostAccess for the GraalJSScriptEngine available in a static final variable instead of creating it for each new engine.
Solution proposed in https://github.com/oracle/graaljs/issues/121#issuecomment-690179954.

Sharing a single engine across all Contexts (as proposed in https://github.com/oracle/graaljs/issues/121#issuecomment-880056648) is not possible, because core expects a ScriptEngine.

* [jsscripting] Close `GraalJSScriptEngine` when `OpenhabGraalJSScriptEngine` is closed

My breakpoint inside the close method of GraalJSScriptEngine did not trigger until this change was made.
