Issue 479: Remove VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT

dEQP-VK.glsl.texture_gather.basic.2d.depth32f.size_pot.compare_less.clamp_to_edge_repeat unconditionally creates a VkImage with VK_FORMAT_D32_SFLOAT and VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT which is optional.
However that the test does not really need VK_IMAGE_USAGE_DEPTH_STENCIL_ATTACHMENT_BIT because the image is not used as D/S attachment, but as SAMPLED and TRANSFER.
