Description

bCastHiddenShadow flag in UPrimitiveComponent doesn't affect ray tracing shadows

Steps to Reproduce

1. Create a new project and enable Ray Tracing
2. Create a empty level and add two meshes (A floor and a smaller cube on top of it)
3. Place a light near the meshes and make sure Cast Ray Tracing Shadows is enabled.
4. Select the eye next to the sphere in the world outlier to hide the object

Result - The hidden object is still casting a shadow
Expected - Hiding the object also removes the shadow
