Steps to reproduce:
1. Open user's attached project "StackingTest.zip"
2. Edit -> Project Settings-> Player-> Other Settings set the Graphics API to Vulkan
3. Build the Project
4. Attach it to RenderDoc
5. Open it and Capture a frame
6. Expand Event Browser
5. Notice that there are 3 same Vulkan Callbacks from Camera

Expected results: Identical camera-stack layer render-pass are combined into 1
Actual results: Each camera-stack layer generate a render-pass separately

Reproducible with: 2020.1.0b4, 2020.2.0a5

Note: Unable to test below 2020.1 due to project braking. Most likely not a regression. Also reproduces with Mobile devices
