Bonsai: guard set_objects_selection against excluded/hidden collections

When an object's collection is excluded or hidden in the view layer,
Object.select_set() and setting view_layer.objects.active both raise
RuntimeError. tool.Blender.set_objects_selection() called them directly
for every object being reselected, so any operator reapplying a prior
selection through it would crash if one of those objects had become
unselectable (e.g. it was moved by the operator into a container whose
collection the user had excluded/hidden), aborting after already
completing the underlying IFC changes.

set_object_selection() (singular) already tolerates this for a single
object. set_objects_selection() now reuses it per object and guards the
active-object assignment the same way, so all 9 existing callers benefit
without each having to pre-filter the selection themselves.

Fixes #7410
