WorldNormal no longer works on deferred decals

The SceneTexture:WorldNormal is not taking in direction for color when used on deferred decals. As a result, the decals using this node always show up as grey.

Tested in 4.21.2 (CL - 4753647), 4.22.1 (CL - 6063286), 4.23 (CL - 6682473)

1. Download the attached project
2. Create a cube in the scene
3. Drag an instance of NewMaterial to the scene
4. Make sure the DecalActor for the NewMaterial is overlapping the cube

Expected: the Colors for the decal would be red, green, and blue based on the direction

Result: All of the colors are gray
