fix(SegmentationStyle): Fix inactive contour visibility and styling. (#5563)

* Opacity, fill and outline properties for active and inactive contours
are now consistent with those for label map segmentations.
The properties for inactive segmentations are applied to BOTH
inactive contours and label maps.

* Activate the selected segmentation for a type when the alpha, outline width, or fill/outline visibility is changed.
