Landscape Far Shadows Interfere With Distance Field Soft Shadows

Landscape far shadows are interfering with the distance field soft shadows causing a conflict, and stopping the distance field soft shadows from rendering at all.

Working as expected in 4.20 CL# 4369336 and 4.21 CL# 4753647

Found in 4.22 CL# 5275346 and 4.23 CL# 5287285

1. Open the Editor
2. Create a landscape
3. Set Skylight and Directional Light to Movable
4. Enable "Generate Mesh Distancefields" and restart the Editor
5. Place a static mesh on the landscape
6. Enable Distancefield Soft Shadows
7. Increase far shadow cascade count in the directional above 1

Results:
The far shadow cascades stop the distance field soft shadows from rendering.

Expected:

Both far shadows and distance field soft shadows should be visible and work together.
