Register Entity, the generic Component wrapper, and Scene as JerryScript classes (modulelist.c ties them together, plus their .d.ts stubs), so scenes/entities can be built from script going forward instead of the JSON scene format. With scripting now the intended authoring path, drop the JSON serialize/deserialize machinery entirely: componentdefinition_t's serialize/deserialize callbacks, every component's *Serialize/ *Deserialize function, entitySerialize/entityDeserialize, sceneSerialize/sceneDeserialize, and the "prefabs/<name>.json"/ "scenes/<name>.json" asset fallback in entityPrefabResolveAndApply/ scenePrefabResolveAndApply (C-coded prefabs only now). physicsshape.c and its test are removed outright since they only existed for this. game.c's test scene now comes from the existing overworldSceneCreate() C builder instead of loading the now-deleted assets/scenes/test.json.
