Removed unused property hints and Object::get_translatable_strings()
* Remove unused `EditorPropertyMember` and related hints, previouly used by
  VisualScript. Such logic should be implemented in the VS module itself.
* As the above broke compatibility with the VS module, clean up the other
  hacks that were still in core in support of VisualScript.
* `PROPERTY_USAGE_INTERNATIONALIZED` was only used in Object's
  `get_translatable_strings()`, which is a legacy function not used anywhere.
  So both are removed.
* Reordered some usage flags after the above removal to minimize the diff.
* General clean up.

Fixes #30203.
