Merge branch 'fix-290-291-ds-advanced' into 'vulkan-cts-1.0'

Fix dEQP-VK.dynamic_state.ds_state.stencil_params_advanced #290, #291

- Add missing barriers to ensure fragment loads wait
- Add LOAD_OP_LOAD for stencil aspect as the data is always needed
- Add TRANSFER_DST usage bit for both color and depth-stencil, as images are target of vmCmdClear* operations
