4.24 Instanced Stereo Distortion Error in ComputeBufferUVDistortion

4.24 moves distortion calculations to the file DistortionCommon.ush and its`ComputeBufferUVDistortion` function. The code in the INSTANCED_STEREO define no longer works as `Interpolants` isn't passed to `ComputeBufferUVDistortion

1. Open a new blank Blueprint project in Unreal 4.24 Preview 2.
2. Enable Instanced Stereo by Navigating to Project Settings-> Engine-Rendering- VR- Instanced Stereo.
3. Create a new Material with a Translucent Blend Mode.
4. Create a Constant node with any value, Apply & Save.

Regression: This behavior does not occur in 4.23.1

Result: Error:  [SM5] /Engine/Private/DistortionCommon.Ush(38,45,-56): error X3004: undeclared identifier 'interpolants'

Expected: No Error.
