Depth attachment not stored in late_fragment_tests
The stencil was stored, but the depth attachment was set to DONT_CARE.
This allows implementations to optimise out the depth store at the end
of the renderpass, when the test is expecting to readback valid depth
values for reference comparison.
Affects:
dEQP-VK.renderpass.suballocation.subpass_dependencies.late_fragment_tests*
Components: Vulkan
VK-GL-CTS issue: 1578
