Motion vectors + TAA. Also the denoiser for RT soft shadows (1 spp grain) and alpha edges. Prerequisite for FSR.

Part of epic #84 (temporal pipeline): needs motion vectors, jitter, history, reactive mask.

Done and tested in-world: motion vectors + jitter (e6410522a9), rigged/attachment motion (a40e2376cc), resolve with reactive mask (6db154a75f); RT soft-shadow noise now varies per frame and uses stratified multi-ray sampling (cafcde2086, 135e5793fa). Enabled with RenderFSAAType 3 (TAA) or RenderVKTAA.
