Cycles: reduce number of synchronizing object prints.

Do it only for meshes/curves since those are potentially slow and need user
feedback to see things are not stuck. For object instances and lights assume
it's fast enough.

Printing too much can have a performance impact on slow Windows command
prompt or when logging complex scene renders.
