- secondary normal is now achieved with two slabs, no fast path for that one which before needed preoject settings anyway.
- coat is only enabled in shader when coverage is >0
- eye is removed from the dynamic case

Basic algorithm:
Estimate the pixel correspondences (motion vectors) to the previous frame where their local patches match the best using non-local means. Then history is combined with the current frame with a temporal low pass filter (exponential moving average & temporal bilaterial filtering). To better control the parameters, we use perception error DeltaE2000. Pixel difference larger than 10 dE is rejected for detail preserving.
How to enable:
Add `r.PathTracing.TemporalDenoiser 1` in MRQ console variables when path tracing denoising is enabled in postprocess volume.

- added optimised clear coat path (hard coded absorption, top F0=0.04 & F90=1, shared normal only).
- This is needed for simple clear coat to perform well and better repsect previous gbuffe rmemory usage.
- SSR handle that change of roughness and F0 on top.
- there will be follow ups: Lumen to be fixed, a few visual mismatch to fix, etc.

This allows to have 'fast'/single layer path eye which support dual normal & caustic computation. This first version does not have SSS profile support and is missing the alternative iris normal decoding. This will be added in subsequent CLs.

* Change material header BSDF to handle a single BSDF type rather than a combination of BSDF type (which isn't supported at the moment.
