Subject: Fix for [#35238] Blender does not save custom orientations from
 "view"

Actually more a feature request... Now create orientations operator has an additional option, use_view, when this one is enabled it will use current view instead of active object to create the new space.

Also made some cleanup (made some funcs static).
