This patch causes the render buffers to be copied to the denoiser device only once before denoising and output/display is then fed from that single buffer on the denoiser device. That way usually all but one copy (from all the render devices to the denoiser device) can be eliminated, provided that the denoiser device is also the display device (in which case interop is used to update the display). As such this patch also adds some logic that tries to ensure the chosen denoiser device is the same as the display device. Differential Revision: https://developer.blender.org/D15657
