[jsscripting] Upgrade to ECMAScript 2022 & Dependency improvements (#14093)

* [jsscripting] Remove asm from dependencies in pom

GraalJS >= 20.3.0 doesn't require org.ow2.asm as compile dependency anymore, see https://mvnrepository.com/artifact/org.graalvm.js/js/20.3.0.

* [jsscripting] Remove dependency org.graalvm.js/js-launcher as it is not required

js-launcher is GraalVM's JavaScript command line interpreter and not required in the addon.
See https://www.graalvm.org/22.1/reference-manual/js/RunOnJDK/.

* [jsscripting] Add missing com.ibm.icu dependency

GraalJS changelog says that it is not required for GraalJS >= 22.0.0 (see 685e5873af/CHANGELOG.md (version-2200)).
But GraalJS 22.3.0 attempts to load classes from it during runtime.

* [jsscripting] Update GraalJS engine options

Compat, as its additional functionality is not used by openhab-js and user code is not expected to use it.

* [jsscripting] Remove com.ibm.icu/icu4j dependency
* [jsscripting] Don't disable Nashorn compat mode as openhab-js requires it for accessors
