feat(editor): Use resource locator at Simple Vector Store memory key, allow cross workflow use (#15421)

Remove workflow isolation from in-memory Simple Vector Store, making it possible to use vector stores created on other workflows. Display all current in-memory vector stores with a resource locator at Memory Key picker.

Note that these vector stores are still intended for non-production development use. Any users of an instance can access data in all in-memory vector stores as they aren't bound to workflows.
