Sergey Sharybin ac20970bc2 Depsgraph: optimize out evaluation of hidden objects
This change makes it so that objects which are temporary hidden from
the viewport (the icon toggle in outliner) do not affect on the
performance of the viewport.

The attached file demonstrates the issue. Before this change hiding
the object does not change FPS, after this change FPS goes high when
the object is hidden.

Changing the object temporary visibility is already expected to tag
scene for bases updates, which flushes down the stream to the object
visibility update. So the only remaining topic was to ensure the
graph does a special round of visibility update on such changes.
