CDD: Add GPU debug layer developer requirement

- This ensures that Vulkan graphics debug tools can connect and
  interact with applications uniformly without requiring root access
  to the device.  Previously they could only discover layers that were
  packaged with the application, or from system locations on rooted
  devices.
- This functionality is covered by CtsGpuToolsHostTestCases
