f97ab2884f [Major] Reduce SSS performance overhead when SSS only occupies a small region (e.g., from 0.7ms to 0.2ms). 
1. Reduce unnecessary UAV Clear with property velocity projection. Only subpass one UAV is cleared conditionally when separable tiles are detected.
            2. Remove subsurface view copy and use tile based recombine.
            3. Mipmaps are generated only when there are many Burley tiles ( default r.SSS.Burley.MinGenerateMipsTileCount to 4000)
[Minor] Rename pass and texture names, and use proper descriptors.
