[jsscripting] Await activation of OSGiScriptExtensionProvider before registering ScriptEngineFactory (openhab#21042)

* [jsscripting] Await activation of OSGiScriptExtensionProvider before registering ScriptEngineFactory

This ensures that OSGiScriptExtensionProvider / `require('@runtime/osgi').bundleContext` is always available when JS ScriptEngines are created.
Fixes issues such as openhab#21014.
