[Feature Request] SingleWaterLayer Materials don't receive shadows with Baked or Partially Dynamic Lighting

Using baked and dynamic lighting produces varying results when implementing SingleWaterLayer Materials.

This was reported and tested in 4.24 Preview 4 (CL-10387632) and reproduced in Main 4.25 (CL-10487445)

1. Download and open the attached project
2. Navigate through the maps to see the different lighting scenarios using SingleWaterLayer

Results: The Water Material is completely black in a 100% baked scene. It doesn't receive any shadowing. When using a Stationary Light, it is lit, but doesn't receive any shadows. It only receives shadows with dynamic lighting

Expected: Always shadowed (baked and dynamic)
