DrawProcedural skips the draw call when "Fake Normal" is checked in Material settings

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scene.unity” Scene
3. In the Project window select “Mat” Material which is in the Assets folder
4. In the Inspector window check the “Fake Normal” checkbox
5. Observe the Scene

Expected result: All 3 cubes are seen
Actual result: Cube under the “DrawProcedural” text is not rendered

Reproducible with: 2020.3.46f1, 2021.3.22f1, 2022.2.13f1, 2023.1.0b10, 2023.2.0a9

Testing environment: Windows 10 Enterprise 21H2

Notes:

• DX12 DrawProcedural (and their variants, e.g. DrawProceduralIndirect) silently drops the draw call, if it (wrongly) thinks that the shader needs to access
  data from a vertex buffer
• This might be the same issue as discussed on the forums since mid-2021, people say this started with 2021.2

• All three cubes use the same material & shader
• On DX11 and Vulkan, everything works more like expected, no matter what's the "Fake Normal" material setting,
  the square is visible
• Switched platform to Android and changed Graphics API to Vulkan and the project crashed with no Stack trace
• See "Shader.shader" comments and actual shader code for more details
• The issue is with ShaderGraph: even if we make it not actually use the declared vertex inputs, due to
  the above issue DX12 still skips the draw call, because it assumes that the shader needs a vertex buffer
