[Vulkan] Inefficient memory barriers (vkCmdCopyBufferToImage)
Steps to reproduce:
1. Open attached project
2. Open SampleScene
3. Build & Run to an Android device
4. Take a RenderDoc capture
5. Observe that behavior occurs in this sequence:
- Barrier VERTEX | FRAGMENT | COMPUTE -> TRANSFER
- vkCmdCopyBufferToImage
- Barrier TRANSFER -> VERTEX | FRAGMENT | COMPUTE
Expected result: the barriers should not force fragment shading to be complete before any vertex shading
