Fix T51652: Cycles - Persistant Images not storing images

Denoising was setting session parameters for every frame, which was detected as
a change and therefore caused a resync.

Since the parameter modification change is only needed for viewport rendering
(which doesn't support denoising anyways) and resyncing after a frame change
(which isn't affected by denoising settings), an easy fix is to just ignore
the denoising parameters like it's currently done with the samples.
