[Vulkan][Metal] Voronoi and Simple Noise slightly different on Vulkan from other Windows APIs, drastically different on Metal
Unity Version: Version 2019.3.0a12 (856a59fec312)
SRP Branch: 955e46e403
Steps to reproduce:
1. Create two Universal projects, one for Vulkan and one for D3D11 (or any other windows API besides Vulkan)
2. Create a new Shadergraph on both
3. Create a Simple Noise or Voronoi node on both
4. for Simple Noise, set the scale to 20. For Voronoi, set the Angle Offset to 5 and the Cell Density to 10.
5. Cycle between the two shadergraphs to see the difference (or check the attached gif)
