Fix T77712: Crash on proxied rig, custom bone shape, driver targeting rig

It turns out that
`DepsgraphNodeBuilder::build_object_data_geometry(Object *object, bool
is_object_visible)` was called for the custom shape with
`is_object_visible=false` when there are drivers, and
`is_object_visible=true` when there aren't any.
