Add experimental spatial de-noise filter on key frames. For forced key frames in particular this helps to make them blend better with the surrounding frames where noise tends to be suppressed by a combination of quantization and alt ref filtering. Currently disabled by default under and IFDEF flag pending wider testing. Change-Id: I971b5cc2b2a4b9e1f11fe06c67ef073f01b25056
