Shader errors are thrown when including Input.hlsl in the custom function

For the final shader and main preview, Input.hlsl is already included. While including this in a custom function node will cause an error, it's limited to the node's preview shader and not the final shader. To circumvent situations like these, you can use the "SHADERGRAPH_PREVIEW" define to branch accordingly.

Reproduction steps:
1. Open the attached “ShaderGraphCustomFunctionBug.zip” project
2. Open the “Assets/MyShaderGraph.shadergraph” shader graph and observe the MySubgraph node
3. Open the “Assets/MyInclude.cginc” file
4. Uncomment the 5 line
5. Save the file (CTRL+S)
6. Reimport the “Assets/MyInclude.cginc” file (Right-click > Reimport)
7. Observe the MySubgraph node
8. Save the shader (CTRL+S)
9. Observe the Console window

Expected result: No errors are thrown
Actual result: Shader errors are thrown
