Compute Shader with RWBuffer<> type throws an error when it is compiled with Vulkan API
Reproduction steps:
1. Open the user's attached "Buffer and RWBuffer dont work in Vulkan.zip"
2. In the Project window select Assets/Resources/NewComputeShader.compute
3. In the Inspector click "Show compiled code"
Expected result: No errors appear in the Inspector
Actual result: "The resource 'Result_origX0X' uses an unsupported type/format at kernel TESTKernel" error appears in the Inspector
Reproducible with: 2020.2.0a13, 2020.3.34f1, 2021.3.3f1, 2022.1.1f1, 2022.2.0a14
Not reproducible with: 2019.4.39f1, 2020.2.0a12
Reproducible on: Windows 10, Windows 11
Could not test on: macOS (Intel) 12.2.1, Vulkan API is not available
Note: Not reproducible with Direct3D11, Direct3D12, and Metal APIs
Workaround: Error does not appear if RWBuffer<> is changed to RWStructuredBuffer<>

Resolution Note:
This is not a bug, but rather because right now our Vulkan backend only accepts single float/int/uint as RWBuffer formats. The work to extend the support for more formats is underway.
