Cycles: Un-pause render when switching to rendered viewport

Browse Source 
Consider switching to rendered shading type as a request to start
rendering, without requiring to un-pause.

This minimizes amount of clicks needed to start rendering after
viewport was paused once, and then shading mode got changed.
