denoise_persist_rgba16f

Carries the frame denoise_temporal_rgba16f resolved into the pair the accumulation is held in across frames — and only for the camera that accumulation belongs to, so a capture or a camera rendering into a texture leaves it as it stands.

The pass itself is @builtin::systems.denoising.dn_persist, which both format variants include — see that module for what the bindings mean and how the camera is compared.

Writes rgba16f; the pair of these covers the formats a filter is built for.
