Export ControlsManagerLayout in overviewControls for vertical-overview extension
Exporting ControlsManagerLayout will be necessary to update vertical-overview to be able to use modules for gnome-shell 45 support.
I do not have permission to fork the repository or create merge requests, so I can't make a request for it, thus, opening it as an issue.
(Sorry if this is below the required quality level for issue creation, it's kind-of my first one)
