Cycles: Fix missing viewport updates after recent changes

We can not access ensured-to-be-evaluated dependency graph from the
render API: some of it is running from within evaluation which makes
it possible for engines to access list of evaluated IDs.

Solved by passing dependency graph to viewport functions, similar to
the final render functions.
