Fixed UnpackShadowType going out of sync with changes made to ShadowBase.cs.

Assets/ScriptableRenderPipeline/HDRenderPipeline/Shadow/Shadow.hlsl

 
 void UnpackShadowType( uint packedShadowType, out uint shadowType, out uint shadowAlgorithm )
 {
-	shadowType		= packedShadowType >> 9;
+	shadowType		= packedShadowType >> 10;
-	shadowType = packedShadowType >> 9;
+	shadowType = packedShadowType >> 10;
 }
