Remove dependence on the NdotL for thickness evaluation for translucency

com.unity.render-pipelines.high-definition/CHANGELOG.md

 
 ### Changed
 - Changed default reflection probe to be 256x256x6 and array size to be 64
+- Removed dependence on the NdotL for thickness evaluation for translucency (based on artist's input)
