InstanceID is not transferred from vertex to domain shader
Steps to reproduce:
1. Open attached Unity Project "923897-TesselationShader.zip"
2. Load Scene "Tesselation x Instancing"
3. Option 1: Select Material "FixedTesselation" and enable "Enable Instancing" in the Inspector
4. Option 2: Select "Instanced Cube" GameObject in the Hierachy and enable it.
Note: the user is using a shader script (modified to support instancing) described in Unity documentation, can be found here:
https://docs.unity3d.com/Manual/SL-SurfaceShaderTessellation.html
Expected result: The instanced object and its material will be displayed correctly
Actual result: Error "Shader error in 'Tessellation Sample': 'disp': output parameter 'v' not completely initialized at line 37 (on d3d11)" is displayed and the material does not work
