New deploy level config: Force global segmentation panel

Why should we prioritize this feature?

Currently the segmentation panel is fixed to display current stack viewport segmentation. If switching to another active viewport with no segmentation, nothing is displayed in the segmentation panel, even if an inactive viewport does have a segmentation.

We should allow a deploy level config that enables the segmentation panel to display all segmentations regardless of active viewport. For now, this will only force display all global segmentations, new design will be required outside of scope for better UI/UX to handle scenarios where the panel needs to display conflicting segmentations.
