Add support for using the Stash (to NLA) and Push Down operators on empty Actions. In the past years, the NLA has seen stability updates that ensure strips are at least a single frame long, and with that even pushing down an empty Action will create a visible (albeit tiny) NLA strip. There doesn't seem to be a practical reason to disallow this any more. Pull Request: https://projects.blender.org/blender/blender/pulls/136604
