Ray Traced Translucency Option Doesn't Work in Post Process Volume.

Found in 4.23 Preview 6 CL# 7848402, and 4.24 CL# 8074192

Working as expected in 4.22 CL# 7053642

This is a regression.

Steps to Reproduce
  1. Open the Editor in DX12
  2. Enable Ray Tracing
  3. Create a translucent Material
  4. Place a Post Process Volume in the scene and enable infinite extent
  5. Place any mesh in the scene and apply the material
  6. Set "Translucency" to Ray Tracing

Translucency will remain as Raster

Ray Traced Translucency would be enabled

The CVar r.RayTracing.Translucency will still enable or disable RT Translucency properly
