Description
Some CTS tests fail with subpass dependencies that depend on late fragment depth testing.
This might be fixable with effort within the implementations.
In the meantime, these use cases can be disabled in CTS and reported as Not Supported, by adding a `VkPhysicalDevicePortabilitySubsetFeaturesKHR:: subpassDependencyLateFragmentTests` capability.
This affects 9 CTS tests:

Research direction
Search the repository for existing VkPhysicalDevicePortabilitySubsetFeaturesKHR capabilities and the listed late_fragment_tests CTS names. Trace how capabilities cause CTS cases to be reported as Not Supported, then add subpassDependencyLateFragmentTests consistently and verify the nine affected tests receive that status.
