UI: hide Viewport Display Bounds for object types that dont have
bounding boxes

These are namely 'LIGHT', 'CAMERA', 'EMPTY', 'SPEAKER' and 'LIGHTPROBE'.

Note that Empties are included here despite the fact that they have
instancing capabilities ('Display As' can be 'Bounds' for example which
then displays all instanced geometry with boundingboxes -- this however
is not meant to work with the 'Bounds' checkbox and the display bounds
type, these are only affective for the object itself, not its instances)
